Using green laser light to make the tiger is must have the effect, because of the specific effects of tiger vary. Let the first thing you say as everyone knows things, animal belonging to the two color instead of a trichromat. In simple terms, the vast majority of animal are color blind. Two color viewer “means the person or animal can only distinguish red and green two colors, blue in; and trichromat can distinguish all the three colors.
Animal behavior science is a theory that says that two of the color of the animal may suddenly see the mobile green laser light is more sensitive, when they suddenly saw a moving object, fear center would be called amygdale brain impulse stimulation to make animal stress reaction, this is when people want to close to the animal should be slowly close.
Of course, this stress response is also different from the animals. Some animals may behave as panic, such as horses, and some animals show confrontation, as we see the cat and green laser light.
So the same way, when you take a green laser light to tease the tiger, as long as it is within the scope of the tiger’s rapid movement, the tiger will respond to stress
Although this new work is a proof of concept, high power laser may have a day can achieve full-color three-dimensional volume update display. These types can be used to display or art museum exhibits, visitors can watch the show around the target in all ways. They are also exploring, to help doctors before surgery visualization the patient’s anatomy or study of the terrain and buildings of the previous target in the military mission.
For the new display bubble phenomenon called high power laser, which is focusing on the femtosecond laser multiphoton absorption occurs at the point. The multiphoton absorption allows researchers to create microbubbles in very precise position by moving the laser focus to a liquid filled container, as a different part a “screen”. The use of high viscosity or dense liquid, to prevent bubbles in the liquid, but once the bubble formation, immediately rise to the top position of the liquid.
When high power laser such as halogen lamp or high power LED light scattering to the foam forms when visual graphics. Researchers led by changing the color of white, red, blue and green to create monochrome images. They also illustrate that the projector illumination graphics can produce different colors in different regions image.
Compared with the one by one to create each bubble, the researchers used a computer generated hologram of the formation of high power laser, vesicle number and shape of let them control. This method can also increase the amount of light scattering from micro bubbles, make the image more bright.
We have introduced the principle of burning laser pointer: plus electronic excitation energy from the valence band to the conduction band semiconductor jump when the electronic conduction band to the valence band, the energy in the light, will be released. A type of laser stimulated radiation is the most basic condition, the excitation energy in two ways, regardless of the use of the methods can produce laser light is applied to electronic light jump; electroluminescence is power electronic applied will jump, in more detail later.
A pair of burning laser pointer applied to the light emitting region, the resonant cavity can actually use a mirror, as shown in Figure three, the beam is reflected back and forth between about two mirrors, constantly through the light emitting region absorb light energy and finally have a resonance effect, so that the light energy amplification.
Burning laser pointer we use titanium sapphire laser as an example, first in sapphire doped titanium atoms are titanium sapphire crystal, placed many high brightness light source in the crystal (around the issue of a certain wavelength light irradiation) to crystal, when the crystals absorb light energy, it will send out another wavelength (color) light.
Burning laser pointer light through about two mirror reflected back and forth, because the reflector design right can penetrate into the 5% light, so will the right by the high energy laser transmitting light emitted by. About two crystal reflecting mirror reflected back and forth, because the mirror design right can penetrate 5% light, so the laser beam will be high energy by right through injection.
The effect of spatial filter is to improve the quality of blue laser pointer, strictly speaking, each node needs to monitor the image transfer in near field and far field. In addition, the input and output wavefront spatial filter is a very important parameter to ensure the basic performance of the laser device, optical element diameter before is relatively small, mainly affected by the wavefront collimation.
As the optical element diameter increases, making alignment aberration introduced by frequency ripple wavefront error will affect the near field and far field distribution, so the monitoring beam quality needs to take into account the near field, far field and wave parameters to complete, such as can be detected at the same time the three parameter is the ideal location of.Blue laser pointer the direction of transmission through one optical element, optical element with wavefront error and wavefront diffraction effect change, near-field and far-field wavefront distortion by the same position, only the “eye”. The “Mami”.
Blue laser pointer detection with the development of SG series device, from the beginning of “Shenguang I measurement of laser parameters are complete, including the detection of laser beam parameters, near field, far field and wave.20 years ago the Shenguang II development process, further optimization of the near field and far field instrument is an important instrument the role of reasonable arrangement of the optical path and beam quality monitoring and control.
Data processing is introduced as the beam filling factor of near field distribution of evaluation parameters, describe blue laser pointer geometric volume and high ratio of beam peak for the rectangular volume. Near field instrument monitoring the Shenguang II optical image transfer in strict accordance with the arrangement, can greatly improve the beam quality.
When laser pens twisted, the hollow channel effect of the helical array in the light, similar to that described by general relativity, when light travels through the stars will occur due to gravitational bending in space.
The optical fiber as an internal laser pens. like pipeline light by wall, usually with a light guide fiber core, the refractive index of glass fiber rate higher than the refractive glass outer layer closed. The refractive index difference will cause the light reflection in the cladding interface, and trapped in tube shaped fiber in the core. The team LED for the first time the light guide without core photonic crystal fiber.
A typical laser pens consists of a piece of glass, a regular periodic array of holes in the glass and air volume. Due to the different refractive index and refractive index with periodic structure. This is the material called crystal, their atoms form a three-dimensional lattice ordered in the crystal salt or for example. In the conventional silicon crystal, such as insulator, conductor and semiconductor, the precise design of 3D structure determines the behavior of electrons.
The three-dimensional structure depends on the optical properties of a laser pens to periodically, in some butterfly wings, this structure determines the butterflies sparkling color. The optical properties to control material is very useful in a wide variety of applications. Developed by Philip Russell and his team of Marx Planck in Erlangen the visible spectra of the photonic crystal fiber can be used to filter specific wavelength or produce super white light.
Brenda created a wavelength of 1550 nm wavelength infrared signal – this is the common optical fiber cable with laser module. Then, he had a “WDM processing” of this signal, this signal can be converged to the same different wavelength of laser beam. After that, he through the lens of low cost on the laser transmission.
In addition, they also play life with the same equipment transmission of television signals. They will be 1 thousand MHz CATV signal input multiplexer; thus, television signals and other data from the same laser module. at the other end, they put a LED TV to watch the received TV channel.
Li Xiage believes that laser module can make data center managers more easily re arrangement of server frame. In this case, all servers need cooling can be placed in the same area, rather than scattered. At present, many large Internet Co are the data center energy consumption costs, one of the most important criteria as room location. For example, Google will be “cheap power” primary condition of the location of a data center.
Of course, it is difficult to evaluate this set of laser module in the end how much energy was saved, and the installation of the laser have enough price is also unknown. Professor Maria spent about $twenty thousand to build a prototype system, but he expects, if big companies are willing to invest, or integrated electronics continue to make a breakthrough, this set of system equipment costs will fall sharply and quickly.
The principle of green laser measurement based on simple geometric relations. The laser beam emitted from the laser diode is irradiated to the measured object surface. The reflected light through a lens, onto a photosensitive element matrix, the photosensitive element can be CCD/CMOS or PSD components. Strength of reflected light on the surface characteristics of the measured object.
The green laser probe to the measured object distance can be accurately obtained by calculation. The triangle rule using this method can obtain micron resolution. According to the different models, the measured data from external or internal controller through a variety of interfaces for evaluation.
Green laser is projected to be measured to form a visible spot on the object, through the spot can probe installation debugging is very simple, so the laser sensor is applied to many fields, become a popular choice for precise distance measurement. According to the different design, the optical measurement principle of maximum allowable measurement distance to 1m. according to the need of measuring tasks you can choose the range, very small, but has high measurement accuracy.
In addition a highly reflective mirror, or analyte, may cause the vertical light return without the formation of diffuse reflection, will also cause the measurement ineffective. So the use of green laser, we must first fully communicate with the manufacturers, not human can be measured results most probably it did not actually happen, but not good. The current international mainstream laser displacement sensor the brand, such as Germany and Japan, Kean m Iridium, will require customers in the selection of laser displacement sensor, notice the measured surface structure and reflective properties.
Green laser application can be well corrected laser module in optical system, to improve the imaging quality of laser pens blue laser pointer, to improve the ability to identify, range of action, it can take one or several small aspheric parts instead of more burning laser pointer, which simplifies the structure of instrument, reduce costs, and effectively reduce the the weight of the instrument.
High power laser green laser light parts in modern high-energy, ICF ignition project, green laser and laser pens and deep space exploration strike system plays an extremely important role, increasingly wide range of applications. Some of these systems due to the use of environmental and related conditions, has very stringent requirements on laser module.
Blue laser pointer traditional processing methods not only in time, efficiency and cost can not meet the requirements, it is more important to burning laser pointer can not be completed as many other materials and high power laser green laser light processing. At the same time, the traditional processing method can not solve complex aspheric surface parts, such as green laser ultra precision machining technology, the problem of conformal curved optical parts.
There is an urgent need to study to adapt to the rapid and efficient laser module, on the other hand, with the development of modern computer technology, laser pens, blue laser pointer, the development of various precision components manufacturing technology and environmental control technology, but also provides technical support for the implementation of the requirements of the burning laser pointer, which may become a reality.
Long life laser module configuration green laser system has been basically close to the free maintenance, in the production process, laser pens grade 1, no other safety protection device.Blue laser pointer system is equipped with a suction device, will not cause the emissions of harmful substances. The control software with easy operation, the burning laser pointer is being replaced the traditional mechanical process, saving the cost of special tools.
High power laser circuit board board and green laser light micro drilling and other fields, the green laser system exhibits a significant technological advantage. According to the thickness of the circuit board of different materials, laser module along the desired contour once or repeatedly cutting. Material is thin, cutting speed faster. If the cumulative laser pens is lower than that of penetrating materials required for blue laser pointer, only scratches on the surface of the material; therefore, can be two-dimensional code or code in the material marking, in order to follow the process of burning laser pointer.
The circuit board of the high power laser for frontback connection between the double plate line, or connection circuit for any layer between the conductive multilayer board. In order to need, after drilling the hole wall is plated with a metal layer. Now using the traditional green laser light has been unable to meet the drilling diameter smaller requirements: although improve the spindle speed, but the radial velocity of green laser can be reduced because the diameter is too small, even unable to complete the requirements of the laser module. in addition, considering the economic level, easy to wear laser pens supplies is a limiting factor.
In the early days, each layer of blue pointer laser circuit has been applied to the multi-layer circuit board.Burning laser pointer through the prepreg is pressed together; according to the circuit design, some regions of the high power laser need to be pressed and then cutting window.
Green laser has some unique characteristics, so that they attract scientists laser module. on the one hand, most of them through the non conducting material, so they can be used for packaging box or by external security laser pens, because they are less than X ray energy, they will not damage human tissue or blue laser pointer.
Burning laser pointer due to the chemical effect of different in different ways, is also used to analyze the different high power laser can be used to characterize the specific substances. This is called the green laser light green laser, this ability, the use of light materials analysis is one of the most promising and challenging laser module.
In order to achieve this goal, laser pens scientists launched a series of to the target object, then observe them and wave interaction after the blue laser pointer. burning laser pointer in eyes with visible light, we see a green type because of light reflection produced in the green high power laser chlorophyll.
The solution lies in the metal structure of new imaging green laser light. green laser and laser module when interacting with each other, they will produce a complex electromagnetic field, which is peculiar to the incident signal. Typically, these delicate areas are ignored, but researchers have realized that they can read out the pattern as laser pens, in order to determine the electromagnetic wave. The whole process can be through the micro chip blue laser pointer to complete, it can read burning laser pointer.
