Two polarization perpendicular laser pens optical fiber polarization beam combiner for a beam of light

Therefore, it is very important that how to efficiently synthesize the sub beam of a multi beam communication signal to a bunch of laser pens. In order to solve this problem, this paper proposes a coherent polarization synthesis technique based on optical fiber devices.laser pens1

Two polarization perpendicular laser pens optical fiber polarization beam combiner for a beam of light, due to changes in the input beam phase difference, beam synthesis of arbitrary polarization. In order to control the synthesis of beam is linearly polarized, to proceed to the next level synthesis or for demodulation of communication signals, the group phase were put forward. Control and polarization control of two methods, and the theoretical analysis and experimental verification.

The use of laser pens cooling technology, molecular cooling for the first time three atoms to near absolute zero (-273.15 C), this is the largest molecular technology so far cooling. Scientists believe that this miracle is expected for the manufacture of molecular quantum computer, but also could become a chemist’s good helper.laser pens3

Laser pens cooling technology has been used to cool a variety of single atomic physicists, but its molecular cooling difficult. In cooling by laser, laser energy and cooling system of the match, the more atoms and molecules contained in the atomic vibration and rotation, more complex, more difficult, the difficulty is cooling the greater.

Laser module is the most favored choice is mainly based on their experience early

At the same time, to optimize the steel and aluminum by pre cut laser module consumption, thereby reducing the cost. However, the most important advantage of tailor welded plate according to local specific requirements for components selection of high strength steel or metal plates with different thickness, so as to achieve the purpose of weight loss. Due to weight loss and reduce the consumption of materials complement each other. The vehicle safety and efficiency also improved.

When the production of TWBs, laser module laser welding mainly used butt weld, which can achieve optimal power transfer and forming characteristics of the ideal. Therefore, the use of laser diode is required in this process, the solid laser or CO2 laser.laser module3

Select a new type of laser module is the first step of renewal and development. In the solid state laser, diode pumped thin disk laser and fiber laser are also considered that the two kinds of laser welding in the field of application has been approved, and has the efficiency of 30%.

First of all, laser module is the most favored choice is mainly based on their experience early. But then decided not to use fiber laser has been tested, but in favor of the fiber coupled diode laser.

Green laser and ozone space research and development and application

Green laser and ozone space research and development and application of laser radar detection system with independent intellectual property rights of fine particles and ozone distributions of rapid on-line monitoring system was successfully developed, breaking a number of key technologies in common, enhancing the innovation capability and core competitiveness of China’s laser radar industry.

For real-time monitoring of atmospheric environment capacity and data analysis to provide a reliable technical means.Green laser also integrates a variety of key technologies, developed several sets of prototype, long-term operation and multi round optimization form of laser radar core technology is mature and stable, through technology transfer and production technology developed industry base.

The formation of green laser system and the production capacity, improve the production rate of laser radar, cultivate the environmental monitoring competitive analysis instruments and emerging industries, breaking the developed countries on laser radar core technology monopoly, reversing the high-end laser radar equipment rely on imported products.

green laser1

Green laser is known as the power equipment in the heart of the transformer oil is an important medium for normal operation of the transformer, an insulating and cooling effect is equivalent to the heart of blood. The detection of transformer equipment is normal, usually from transformer oil samples and standard oil on the use of the analysis of the different gas content to reach a conclusion.

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.

green laser light1

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.

High power laser is no need to prepare weapons if you can launch it

High power laser is no need to prepare weapons if you can launch it, with today’s technology is inevitable, but once the need to recharge, then from the charge to the launch always has time difference, high energy charge during the reaction and should have a certain radiation or electromagnetic wave leak out, then should be detected, and the warning or escape. In addition, any active type target may be found and evade.

Someone mentioned in the movie high power laser is a section of the line, the reality of the laser weapon is also possible, because as far as possible to improve the instantaneous power, laser pulse modulation into the state, is the most effective way to the United States. Remote laser weapons

high power laser2

First of all, the power of high power laser and related parameters, I have not found on the Internet to, but can determine the power of the laser is more than the scope of the human can bear, after all has learned that this is a “red” laser, visible light laser is inevitable in eye safe wavelength, and can achieve 30 meters of effectiveness.

High power laser did not seem to be required. The laser laser is photon transitions of atomic / molecular release. The excimer laser and the ultraviolet light source, atoms, molecules have been excited into a plasma state, didn’t we generally assume that the “excited state”, is from the outside level transitions to the ground state, said it is also not what laser, error.
