Green Alignment Lasers
There is quite mature 532nm green DPSS laser tech, which is not only developed into a very simple green laser pointer. On basis of constant technical innovation by laser tech engineer, it is manufactured into advanced green alignment laser. It is not simply used as a temporary presentation, but mainly workable for providing users high accuracy green laser dot, line and cross laser source generation in various industrial mechanical processing works.
Green Laser Module
Comparing with direct diode emission laser device, green laser module employed by 532nm green DPSS laser tech just gets totally different structure design. This green laser device combines laser crystal and nonlinear crystal together, utilizing 808nm wavelength laser diode pumped laser light through crystal (YVO4 crystal), generating 1064nm wavelength. After multiplier effect of nonlinear crystal can produce 532nm green laser. The quite complex structure made 532nm green laser module gets the most sensitive color green laser light, easily absorbed by eyes, making sure of the brightest green laser beam emission in all presentation, industrial inspection and mechanical processing etc.
Green Line Laser Module
Among all visible lasers, 532nm green line laser module is just making the most sensitive color green laser light in all kind of industrial alignment work. It makes the best use of 532nm green DPSS laser tech, thus this advanced green line measuring tool is able to generate extremely bright and visible green reference line at both close distance and long distance working occasions.
Safe Use of Green Laser Pointer
5mW green laser pointer belongs to Class IIIa laser with 532nm wavelength, uses two AAA batteries. This type of green laser projects 532nm green laser beam with high brightness, so it is extremely dangerous to eyes, especially high powered lasers. In many countries and regions, only allow 5mW green laser pointer.
Varieties of Laser Pointers
Early laser pointer only uses 633nm helium-neon (HeNe) gas laser, typically for generating power of not exceeding 1mW laser beam. The cheapest laser pointer uses near 670nm/650nm dark red laser diode. Slightly more expensive laser pointer uses 635nm red laser diode, with near orange red color laser light. 635nm wavelength is much more easily recognized by human eyes. At the same time, there are other colors of laser pointers, the most common is the wavelength of 532nm green laser pointer.
3 Reasons Cause Laser Pointer not Burn
In various high tech and entertainment working fields, laser pointers are always widely used in every corner of the world. Someone might use a laser pointer without any problem more than 2 years. However, laser pointer might also burn out after very short term. Besides self problems of laser pointer, it is also very important to make proper operation of this laser gadget.
