The super bright laser light of green laser pointer would do harm tohuman beings

The super bright laser light of green laser pointer would do harm to human beings and animals. Laser processing systems and computer numerical control technology may constitute a highly efficient automated processing equipment, can play a variety of text, symbols and designs, easy to use marking software design patterns, change tag content, adapt to modern production of high efficiency, fast-paced requirements; 5 . Laser processing is not pollution, is a clean and pollution-free high environmental processing technology; laser marking technology has been widely used in industries for high-quality, efficient, pollution-free and low cost of modern processing has opened up broad prospects.

so that heavier than air aircraft a reality; the mid-1940s to 1950s, the theory of compressible gas dynamics, rapid development, especially transonic area legal discovery and swept-wing new proposal of the concept, to help people break the "sound barrier" to achieve transonic and supersonic flight; the mid-1950s developed the superior performance of the first generation of fighter aircraft, such as the United States, F86, F100, Soviet Mig15 , Mig19 and so on.The cost of green laser pointer production is relatively low. During World War II, the demand for military aviation and missile weapons, the emergence and put into use, have contributed to the higher impact speed. 50 years later, began the development of supersonic aerodynamics new era of second-generation performance of more advanced fighter aircraft have been put into use, such as: the United States, F4, F104, Soviet Mig21, Mig23, French Mirage 3 and so on. (3) 1957 Soviet Union launched the world's first Earth satellite, 1961, the first manned spaceship "Vostok" launch, is considered the beginning of the space age.
The use of green green laser led could be influenced by temperature.Laser diode pumped solid state laser (DPSS laser) is widely used in military field, the laser is an important research direction, present, due to increased manufacturing output devices, operating life and operating frequency Q-switched, diode-pumped Nd: YAG laser technology continues to mature, active in the field have Amoco Laser, Coherent, Lightwave Electronics Corporation, Maikeleke company, Spectra-Physics Laser Diode Systems. 3 semiconductor laser diode semiconductor laser diode lasers have become an important direction of development, which is due to high-power diode laser pumped solid-state lasers can be used.
