Using a polarized pump-probe technique, we studied the continuous-wave absorption and emission polarization anisotropy of Cr4+:YAG crystals and modeled the ground state absorption and excited state absorption loss. We propose a twisted mode laser cavity to compensate for this anisotropic loss and achieve narrow linewidth output.
