Green laser pointer can be used in pitch-dark nights

He has been actively advocating to carry out this new technology in a short period of time, the combination of innovative young team to improve the brightness of the light unit color, coherence of ideas and experimental program   200mw laser pointer . Advent of the world's first laser in 1960. The summer of 1961, the king of the river under the auspices of, the first ruby laser was successfully developed. After a few short years, laser technology rapid development, resulting in a number of advanced achievements. Various types of solid, gas, semiconductor, and chemical lasers have been successfully developed. In basic research and key technologies, a series of new concepts, new methods and new technologies (such as the cavity Q-mutation and the rotating mirror Q, traveling-wave amplification, the use of rhenium Department of ions, free electron oscillation radiation, etc.) have put forward and get implementation, many of them original.   green laser pointer is normally varnished with superior oil paint.
At the same time as the new light source with high brightness, high directivity, high-quality, outstanding features, the laser quickly used in various technical fields, showing strong vitality and competitiveness. Communications, laser show transmission of television images, in September 1964, November 1964, call of 3 to 30 km. Industry, in May 1965 laser drilling machine for drawing die punching production, access to significant economic benefits. Medicine, laser retinal welding carried out on animals and clinical trials in June 1965. National defense, in December 1965 to develop successful laser diffuse reflectance rangefinder (accuracy of 10 m / 10 km), developed a remote control pulse laser Doppler velocimetry in April 1966. The shooting distance of green ray     laser pointer is longer.
It can be said, in the initial stage of China's rapid development of laser technology, both the quantity and quality, and international levels close to an innovative technology can so quickly catch up with the advanced in the world, rare in the history of the development of modern science and technology in China . These achievements, especially the physical ideas, technical solutions successfully into practical laser devices, mainly thanks to the comprehensive ability and a solid foundation of the-ray machines in technical optics, precision machinery and electronics technologies accumulated over the years. The development of a new technology, there is not enough technical support is difficult to form a climate.   green laser pointer  can be used in pitch-dark nights.
The key projects to drive the development of laser technology, laser science and technology from the outset has been the leadership and scientific management departments attach great importance. At that time the Chinese Academy of Sciences, Zhang Jinfu, proposed the idea to build a professional Laser Institute, soon to be approved by the State Science and Technology Commission, the State Planning Commission. Nie Vice Premier in charge of science and technology instruction: Research Institute to be built in Shanghai, Shanghai has a good industrial base, and is conducive to the development of this new technology. In 1964, China's first, was the world's first laser technology, the Professional Institute - Shanghai Institute of Optics and Precision Machinery Research Institute (referred to as the "Shanghai-ray machine") was established. National Laser Conference held in Shanghai in December of that year, Zhang Jinfu, Yan Jici attend and chair the meeting, submitted by 140 representatives of 103 academic reports. The wilderness explorers also can use  green laser pointer  as a tool for seeking help when they get lost.  Started in 1964, 6403, "high-energy neodymium glass laser system, in 1965 began to study high-power laser systems and nuclear fusion research, as well as enacted in 1966 to develop 15 kinds of military laser machine and other key projects, due to technical and difficult, powerful traction and driving all aspects of laser technology development in China. Laser science and technology in China, although it suffered a decade-long calamity of the "Cultural Revolution", but by means of the support of key projects, is still struggling to survive down and made valuable progress. ".1964 Start of the 6403 high-energy neodymium glass laser system, and finally to determine the thermal effect is technically the fundamental technical barriers to dismount in 1976.  green laser is a really good tool for the customer to hold a conference.
