Er:YAG is an excellent laser crystal which lasers at 2.94um.This wavelength is the most readily absorbed into water and hydroxylapatite of all existing wavelengths and is considered a highly surface cutting laser. It is a well known material for medical applications.
Advantages:
High slope efficiency
Operates well at room temperature
Wide Pump Bands (600-800nm)
Operate in a relatively eye-safe wavelength range
