The use life of this kind of green laser pen is much longer others

Thus caused by the heat affected zone is very small, in the coating Cheng Zhongji material only a small region and the coating material with melting to produce the effect of metallographic bond. Moreover, the process of heat input can be precise control of the produce diluted, so to prevent product deformation, while the least impact on the substrate material [10] material nature. 3.7 laser drilling of the laser cladding diagram for hardness, high melting point materials such as Bao laser processing technology advantages and disadvantages of laser processing technology as an emerging technology for its own advantage standing proudly in the production of our lives, in order to our lives to produce a wide range of convenient services. green laser pen can work well during the whole period of the use life ofgreen laser pen.
Due to limited space, no more be introduced Overall, the biggest advantages of laser processing technology is the ability to accumulate in a small range of very high energy, the biggest drawback is the price of the laser is too expensive. The future development trend of laser processing technology due to the continuous improvement of the quality of life, the requirements of the laser processing technology is also increasing. Do not use traditional laser processing technology, the use of more advanced laser processing technology, that is precision laser processing technology.
When the metal surface is heated to just below the melting point of the critical transition temperature, the metal surface rapidly austenitized and then rapid self-quenching, and then to get a high hardness, wear resistance and good fine organization [8]. Laser heat treatment technology can also be selective hardening of large parts of the surface and the complex parts of the local, to solve almost all problems in parts of the surface. Stone, diamond drilling, the normal process and not full demand at this time need to rely on laser drilling. The laser beam is highly concentrated in space and time, which uses the lens, the spot diameter is reduced to the micron level, to get 105-1015 watts / square cm of the laser power density [11]. The multi-laser green laser pointer will have more functions.
In July the same year, Deng Ximing, developed the first He-Ne laser. In December, Wangshou Wu developed the first GaAs homojunction semiconductor laser. 1964, re-Yee, developed the first pulse of Ar + laser. 1965, Wang Runwen etc. successfully developed China’s first CO2 molecular laser. In 1966, Deng Ximing, developed China’s first the CH3I chemical lasers. In July the same year, the flexor dry Chinese [3] successfully developed China’s first YAG laser. At this point, the laser processing technology development in the gradual invention of advanced laser, but its development speed is enough to astound the world. Development and application of laser processing technology has been the history of 53 years from Townes and Xiaoluo’s classic paper published. The worker can simply press the pagedown button of green laser pen.
