Green laser pointers has the very special design

battery is one of the most commonly used batteries for green laser pointers
The good momentum of development of opto-electronics industry across the country, there are many provinces and cities are under construction or planned construction of the optoelectronic industry base or campus with local characteristics. In February 2002, the State Planning Commission released a notice on the organization and implementation of high-tech industry photoelectron special ", and from 2002 began to be three years of the organization and implementation of high-tech industry photoelectron special to support the optoelectronic industry base formation. Ministry of Science and Technology SME Technology Innovation Fund Management Center in 2003 focus on supporting the photonics project, including seven kinds of optical and electrical integration of technology products, LED, intraocular lens, optical functional ceramic materials, optoelectronic devices, and a new laser treatment technology and equipment, etc..  green laser pointers  has the very special design.
In July 2003 the Ministry of Science and Technology and the Ministry of Commerce jointly issued encourage foreign investment in high-tech product catalog, which further clarify the areas of foreign investment photoelectron. 2003, the Ministry of Science and Technology is promoting a major project - National Semiconductor Lighting Project, will invest 10 billion used to guide enterprises breakthrough semiconductor lighting technologies, establish a development base in Dalian, Xiamen, Shanghai and Nanchang to accelerate the formation of the Chinese semiconductor lighting industry. The development of China's optoelectronics industry has begun to take shape, but still in its infancy, and rapid development, the increasing proportion of the output value of global optoelectronics. According to statistics, the global optoelectronics market grew from $ 107.5 billion in 1996 rose to $ 176.6 billion in 2000. 
Also provides an unprecedented tool for the realization of new materials or new functional surface. Created by laser cladding melt in high temperature gradient away from the equilibrium of the fast-cooling conditions, the solidification microstructure formation of a large number of supersaturated solid solution, metastable phase or a new phase, has been a large number of Institute confirmed. It provides manufacturing functionally graded situ particle reinforced composite layer of a new thermodynamic and kinetic conditions. The laser cladding technology to prepare new materials under extreme conditions, failure of parts to repair and re-manufacturing, an important foundation for the direct manufacturing of metal parts by the world scientific community and enterprises attach great importance to many. The customer thinks that the design of  green laser pointers  should be further improved.It means that the diameter of this kind of battery of  green laser pointers is 15mm
