Different from the science fiction movie scene, the laser beam generated by green laser light

Different from the science fiction movie scene, the laser beam generated by  green laser light, you can only see the target was hit after the injury, but did not see the actual beam. It is the “invisible killer”, it is possible to change the future war thinking, to win the war have a decisive impact.

Killing with Kindness, from.2000 to China years of Taoism, mankind has been the dream of the weak green laser light put the enemy into a sword. In 214 BC, the ancient Rome fleet besieged the ancient Greek Sura City, of vital importance occasion, Archimedes used the principle of focusing lens energy convergence, the ancient Rome fleet sailing burned.

With the in-depth study of the proposed optical stimulated radiation theory. After the Soviet Union and the United States the unremitting efforts of scientists, in 1960, the first ruby green laser light in American physicist Theodore Maiman’s laboratory was born. The advent of this product, makes use of the laser beam along a certain direction to attack possible.

Because green laser light has high energy monochromaticity, coherence characteristics and good direction, soon to be a weapons manufacturer, is used in various weapon systems, and has proven its value in.20 century 70s in various wars, laser guided bombs are used to guide the United States, “gem road” series the laser guided bomb in Vietnam clap.

There is also a can not ignore the phenomenon, it is called the green laser light

When an electron is in the excited state, it will behave like a bunch of waves. When two states from the waves interfere with each other, it will leave the so-called “fingerprint” in the femtosecond level. The real quantum effect will be regarded as a new, controllable oscillator the frequency and direction. And the key lies in the level of green laser light, femtosecond fast enough, can enter in the electronic excited state space to intercept it, let it be used to stack, to achieve more operations.

We know that the green laser light by different materials of several superimposed layers, they are orderly stacked together as electronic components. These components are very small, small enough to only use the microscope to see them. In the square grid acts as a switch, control calculation for electronic components. The distance is calculated by nano the distance between each other, so they are more small, a chip can be placed in the more things.green laser light3

After why the process becomes more and more small, the performance can not only become more powerful, energy consumption will become low? Green laser light distance will make the current capacity of the transistor terminal is reduced, enhance the exchange frequency. When the electronic signal switching transistor, its energy consumption and the current capacity is directly related to energy consumption so naturally lower.green laser light2

There is also a can not ignore the phenomenon, it is called the green laser light. when the chip process is less than a certain degree, it will no longer be semiconductor electronic bound, the latter suddenly started smoothly. We need to control the electronic, in order to achieve open and close, which is 0 and 1 can not be achieved if the “0” so, the modern computer mentain system will cease to exist.

Why is green laser light (or its reflection) will look grainy?

When the teacher asked the question of laser principle, the teacher praised me to observe carefully, then tell me this is the green laser light speckle interference phenomenon, because of the special high coherence laser. Gauss beam just shows a cross-section of the laser light intensity on the part of Gauss branch, and the scattered Never mind spot.

green laser light1

The particle state was named “green laser light“. The intensity of speckle pattern is random, can be generated by laser in rough surface reflection or laser through inhomogeneous media. Because most of the surface is rough on the wavelength of light, due to the high coherence laser, when light reflected from the surface of the object. Each point on the object to the appropriate distance of observation point vibration is coherent.

Green laser light is due to photons of frequency, phase and amplitude are the same, each encounter can interfere. Due to surface roughness, a beam of photons in the laser will be rough surface reflection to run around, so it encounters the same phase of the photon, the meeting place will brighten, meet the photon anti phase the place is dark.

The “green laser light” I was not very strict, but the expression of “a small light” laser beam inside the light. In the process of communication, the initial phase (shaking position start) is the same, but the instantaneous phase (the current position of the vibration transmission (with) go forward the process of continuous) to 2 pi (a circle) and the cycle of change.

Computer controlled green laser light scanning the surface of photosensitive resin as raw material

Scanning is to produce light polymerization and curing area of green laser light, forming part of a thin layer. The table down a thick layer of distance, so that the cured resin surface and then deposited on a new layer of liquid resin, the scanning process, the next layer is repeated until the entire prototype manufacturing. Since the light polymerization is based on the interaction of light and not based on the action of heat, so the lower power laser source only at work.green laser light1

In addition, because there is no thermal diffusion, the chain reaction and can better control, to ensure that green laser light does not occur at the laser point, so the high processing precision, good surface quality, the utilization rate of raw materials is close to 100%, can make complicated shape, fine parts, high efficiency. For the larger size of the parts. It can be used to block forming and bonding method of production.

In the automobile body manufacturing application green laser light can produce precision casting mold with the required proportion, which cast a certain proportion of the body metal model, the metal model can be used in wind tunnel and collision test, thus completing the final evaluation of the body, to determine whether the design is reasonable.

For the green laser light test of intake pipe inlet pipe is composed of the inner shape of free surface is very complex, it is to improve the efficiency of charging, have very important influence on the combustion process. In the design process, need to do airway test of different air inlet pipe of the scheme, the traditional method is to use the method of manual processing by dozens of section describe the wood or plaster mold.

Because the green laser light cat has tigers and cats animal, so it is curious how funny the tiger will take the laser pen?

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.green laser light1

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.green laser light3

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
