● Long lifetime
● High damage threshold
● High stability
● High reliability
Cr4+: YAG is an excellent saturable absorption material. It has strong absorption at the wavelength from 0.8～1.2μm and has the advantages of high melting point, damage resistance, and good thermal conductivity. It is often used as passive Q-switch for 0.8～1.2μm lasers.
