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 also derive transmission formulas for specific incident surfaces of (100)-, (110)-, and (111)-planes. In order to prove our model, we examined the polarization dependence in the transmittance of (110)-cut Cr4+:YAG. With the consideration of pump depletion in Cr4+:YAG, we succeeded to explain the polarization dependence that is consistent with past spectroscopic parameters of Cr4+:YAG.
