EYE SAFE LASER CRYSTAL SECRETS

The two.0 µm wavelength area also coincides with a strong absorption line of water vapor. This tends to make Tm:YAG exceptionally well suited for atmospheric sensing and LIDAR purposes, mainly because it can provide exact and trusted data about atmospheric problems.The battle of eye-safe laser crystals, Yb:Er:glass and Tm:YAG, is just not much a f
