The teacher gives laser pointers back to the student

The teacher gives laser pointers back to the student.
Former Soviet scientists H.Γ. Basov in 1960 invented the semiconductor laser. Semiconductor laser structure is usually from the P layer, N layer and the formation of double-heterostructure active layer. Its characteristics are: small size, high coupling efficiency, fast response, wavelength, and size and fiber size adapter, can be directly modulated, coherent and good. According to the Chinese Academy of Sciences News, Physics, Chinese Academy of Sciences Wang Duo through research and development team for their efforts, the first time a large area excimer laser energy for the direct measurement of the effective measuring diameter 100mm, the pyroelectric detector the size of the laser for the world. The student asks the parents to buy laser pointers for him.
Following discussions with the China Institute of Atomic Energy and the relevant experts at the national laboratory tests showed that this system in different energy regions (10-20J and 100-200mJ) have reached the desired specifications. According to reports, the laser fusion research is a promising energy development issues, laser controlled thermonuclear fusion reaction is bound to bring a new twist to human life. Laser fusion research in the military also has an important significance. In laser fusion experiments, especially in the indirect driven fusion research, in order to produce strong radiation-driven market, people are seeking a high X-ray conversion efficiency, good radiation transport environment, the best of the radiation-driven field. In the course of these studies, the energy of the excimer laser for direct monitoring and research is very important. The student asks the teacher to return laser pointers .
The study results showed that the project's research and development in addition to the strength of the products have been developed and constantly open up the market, the countries are developing applications for the needs of the project also has the commitment and development capabilities. Modern society, an increasingly important role of information, who controls the information more quickly, more accurately, the more rich, who will be more to take the initiative, will have more chance of success. Laser led to the emergence of an information revolution, from VCD, DVD disc to the laser illumination, the laser has greatly enhanced the efficiency of use, and easy for people to save and retrieve information, "laser revolution" significance. Space and time controlled laser controlled well, the object of processing the material, shape, size and processing environment of freedom are large, especially for automated processing, laser processing systems and computer numerical control technology may constitute a highly efficient automated processing equipment, has become the key enterprises in-time production techniques for high-quality, efficient and low-cost processing has opened up broad prospects.
