Er:YAG Crystals
● High slope efficiency
● Operate well at room temperature
● Eye-safe laser wavelength
 
Erbium-doped yttrium aluminum garnet or Er:YAG crystals is an excellent laser crystal which lasers at 2.94 μm, This wavelength is the most readily absorbed into water and hydroxylapatite of all existing wavelengths and is considered a highly surface cutting laser. The 2.94μm is a eye-safe wavelength, which makes Er:YAG crystals  widely be used in medical applications as dental (hard tissues), orthopedics, etc.
