The life time of laser pointer is the main concern of the laser pointer
A monopolistic position in the large-scale production of nonlinear optical crystals such as LiNbO3. Small-scale variety of materials such as KTP, BBO, LBO, China, Lithuania, accounting for a dominant position. In device fabrication, due to the strong overall technical strength, industrial foundation, the United States, Europe and other developed countries has the decisive advantage status. China and other developed countries to developed countries can only provide crystal materials to earn a little profit. Market demand analysis of the laser crystal material is pretty sure that a laser, optoelectronics, military, and other industries closely related industries by the development of these industries and the impact of changes is very large. With the rapid development of the last century the world wave of information technology and photonics technology is widely adopted. It is the laser beam color or appearance of  laser pointer .
Domestic and international market surge in demand for nonlinear optical crystal for optoelectronic functional crystal. In recent years, sales of the nonlinear optical crystal around the world each year more than 400 million U.S. dollars, the demand for traditional nonlinear crystal is still increasing year by year, the next few years the market growth rate of around 15% -30%. Laser crystal component in the modulation switch and remote communications, information processing and entertainment in three areas showed a trend of accelerated development. The medical field of solid-state lasers is another important market for the nonlinear optical crystal, the main applications of KTP, of KDP and BBO crystals of CLBO will be a large number of applications. Because the medical industry, the rapid development of the laser, driven by demand for KTP nonlinear optical crystal is growing rapidly. This kind of laser pointer  needs two pieces of rechargeable batteries.
Chapter 5: favorable factors and negative factors of the development of the industry (a) Advantages (1) the core patents and other intellectual property rights. IOL materials: to maintain international leadership in the ultraviolet DUV nonlinear optical crystal materials and artificial micro-structure of nonlinear optical crystal materials research, there are several important nonlinear optical crystal materials is invented by Chinese scientists, and has independent intellectual property rights; a variety of artificial crystal growth technology to the international advanced level, some important crystal to meet the domestic demand for major projects, high-tech crystal has formed a product. Lasers: solid-state laser devices and applied research in China with foreign countries have the basic synchronization, medium and small power green solid-state lasers have been mass production capability.
