What is a green diode laser?
Green diode laser is projecting green spectral regions, roughly covering wide wavelength range of 500nm to 570nm, including 505nm, 515nm, 520nm. It is a laser diode that uses semiconductors, not the same as formally used 532nm green DPSS laser system. Direct diode based green laser diode module and green laser pointer are offering high level of laser beam stability, low noise, and high modulation etc.
Where can I buy a green laser pointer?
While, before choosing an ideal green laser pointer, you have been surfing online or seeking for suggestions with someone else. A qualified laser pen should not only get reliable quality, but also reliable after sale services. Low price is not the only one choice for users. It should be designed with elegant and durable shell, long lasting and good quality green laser beam and green laser dot emission of laser beam aperture.
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.
Top 10 Problems of Laser Pointers
1. What is the difference between red laser and green laser?
Red laser gets wavelength of 635nm and 650nm, and green laser gets wavelength of 515nm, 520nm and 532nm. Different wavelength laser gets different color laser beam and light spot in operation.
