Tag 'blue laser pointer'
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.
There are wide choices of blue lasers for laser amateurs and researchers. Besides formal application for entertainment and simple presentation, blue laser pointer is even more workable for high tech working fields. For instance, 450nm blue laser pointer can be used to make presentation in high definition blue ray players, laser show, environmental monitoring, electronic equipment, medical diagnostics, laser activated paint etc.
1. What is the difference from 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.
406nm blue laser is emitting the most charming sapphire laser beam on the earth. It is totally different from 473nm blue laser. It is just emitting the most special blue laser beam from finished 460nm blue laser diode. This laser diode made laser pointer can be easily designed with portable pen design.
