Cr4+:YAG

● Long lifetime
● High damage threshold
● High stability
● High reliability

EMAIL

Cr4+: YAG is an excellent saturable absorption material. It has strong absorption at the wavelength from 0.81.2μm and has the advantages of high melting point, damage resistance, and good thermal conductivity. It is often used as passive Q-switch for 0.81.2μm lasers.
