If I were you guys, I will not tangle around with this kind of laser! It is very dangerous due to the unique wavelength spectrum that a beam reflection may burn your retina without proper google wearing!
The blue or the green laser is synthesized by applying an infrared 808nm laser beam through a crystal. The 808nm is nasty and we shouldn't touch it at all. It could ended up losing your eyesight or damage to some extend.
Unless you have it installed in enclosed system, otherwise stay away!
