The user is inspecting the parameter of Green Laser Pointer listed in the table

Since then, many laboratories the world have been involved in the development of a fierce competition to see who can successfully build and operate the world's first laser. In 1960, the American physicist Theodore Maiman in Miami, Florida ? research laboratory, barely won the worldwide development of competition. He used to stimulate a high-strength flash tube inside the ruby crystal of chromium atoms, resulting in a considerable concentration of the thin red beam of light, when it is fired at a certain point, it can reach higher temperatures than the sun. The proper maintenance of Green Laser Pointer can be mastered easily.
"Maiman design" caused the scientific community's shock and suspicion, because scientists have been looking and looking forward to a helium-neon laser. Although Maiman introduced the first practical laser scientists in the field, but in court, on in the end who invented the technology debate, once aroused much controversy. One contender is the "Laser" ("stimulated emission type optical frequency amplifiers," the acronym) ? Gordon Gould, inventor of the term. He studied at Columbia University Ph.D. 1957, made the word. At the same time, the inventor of the maser Townes and Xiao Luo also developed the concept of the laser. Final decision by the court, Townes paperwork for research in Gould as early as 9 months to become the winner. The parameter of Laser Pointer should be carefully determined.
But Maiman's invention of the laser power has not been shaken. December 1960, Iranian-born American scientist Jia Wan rate finally succeeded in making people and running the world's first gas laser - He-Ne laser. In 1962, there are three groups of researchers almost simultaneously invented the semiconductor laser. In 1966, scientists have developed into a range of wavelengths can be continuously adjusted in the organic dye laser. In addition, the output energy, high power, and do not rely on the grid of chemical lasers have come out. As with all the salient features of the laser, which was soon used in industry, agriculture, precision measurement and detection, communications and information processing, medical, military and other areas, and in many areas caused a revolutionary breakthrough. The drawing of Green Laser Pointer will be revised after being studied carefully if necessary.
For example, people use laser focus and high energy, a variety of materials can be processed, a needle can be drilled in 200 holes; laser on the body as a biological cause irritation, mutation, burning, evaporation and other effects means, in medicine, agriculture, practical application and achieved good results; in the communications field, a column with a laser optical signal transmission cable can carry the equivalent of 20 000 the amount of information carried by copper wire telephone; laser in the military With the exception for communications, night vision, warning, distance, etc., the variety of laser weapons and laser-guided weapons has also been put into practical use. In the future, laser technology with the human further research and development. Some clause of Green Laser Pointer agreement should be simplified.  Will further improve laser performance, the cost will be further reduced, but it will continue to expand the scope of application is, and will play an increasingly significant role. Laser pointer is the use of laser as an indicator of small, low-power laser, a general civilian goods, also known as laser pointer, Pointer pen. Is a versatile product: teaching, research units as teaching, research papers, conferences and so forth with the use of video equipment as instructed; military units with large-screen command system for instructions; tourism units for guided tours; construction and renovation supervision units for construction, renovation acceptance of instructions and so on. Some cases can also be fixed as a directional tool; also as a gift. Several items should be added the  Green Laser Pointer agreement.
