the high power laser pointer is in the torch appearance

Normally, the high power  laser pointer  is in the torch appearance.
The development and application of the laser crystal is a measure of one of the important indicator of a national high-tech development. With the development of photonics technology and the increasingly widespread application of the laser crystal material also raised higher, the updated requirements. Crystal material can be used for laser frequency conversion, expansion of the laser wavelength; used to modulate the laser intensity, phase; laser holographic storage signal, eliminating the wavefront domain becomes self-pumped phase conjugation. Therefore, the nonlinear optical crystal is the indispensable key materials in high-tech and modern military technology, the developed countries are on the priority development location, and included in the respective high-tech development plan as an important strategic measure to to give a high degree of attention and support. The parameters and performances of  laser pointer can meet all requirements.
Laser crystals, devices and applications throughout the field of scientific and technological level of developed countries such as the United States, Britain, living in the world, from the first principle, exploration of new materials, device development, they have made an important contribution. In the production of the laser crystal materials, Japan, China, and the former Soviet Union countries such as Russia, Ukraine, Lithuania, occupies an important position, and the United States and some European countries are mainly focused in the nonlinear crystal devices and equipment manufacturing . The laser crystal device is the core component of the trichromatic laser products, and higher labor value-added. Our country is an international leader in the research and development, and at the same time with independent intellectual property rights. The green laser beam of  laser pointer  is much brighter.
It is a rare opportunity involved in the product areas in China. The financial crisis is over almost the past two years, but its impact has not gone. Countries around the world looking for countermeasures to completely resolve this issue. - Laser crystal material as a new industry segments in the complex case, also caused a lot of adverse effects. Specific background is as follows: 1: economic policy under the premise of monetary easing, the laser crystal materials demand has decreased. 2: a large number of new production projects, has been facing new competition. 3: The appreciation of the RMB, the Chinese laser crystal material manufacturers export facing a huge dilemma. 4: Raw materials prices substantially, the impact to the production of corporate purchasing. It is the laser torch  laser pointer whose power is too high.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%.
