Simultaneous effects of gain and loss anisotropies on the thresholds of a bipolarization fiber laser.
We study, both experimentally and theoretically, the threshold properties of the polarized modes in Nd(3+)-doped fiber lasers. We demonstrate the influence of the gain anisotropy induced by the pump polarization and of the loss anisotropy induced by the cavity mirror tilt. An understanding of these two phenomena reveals the microscopic anisotropies of the ion for both the pump and laser transitions.
