Polarization dependence of saturable absorption in Cr⁴⁺:YAG was investigated. We theoretically proposed its general analytical formula expressed in terms of the intensity and the polarization angle of the pump beam. We experimentally proved our model by means of the transmission of (110)-cut Cr⁴⁺:YAG with initial transmittance of 75% and 1-W Nd:YAG laser as a pump source.
