THE BASIC PRINCIPLES OF EYE SAFE LASER CRYSTAL

The two.0 µm wavelength region also coincides with a solid absorption line of water vapor. This tends to make Tm:YAG extremely suited to atmospheric sensing and LIDAR purposes, mainly because it can offer accurate and responsible information about atmospheric circumstances.The struggle of eye-safe laser crystals, Yb:Er:glass and Tm:YAG, is just no
