Paper Abstract

We study the time evolution of the polarization state of the light emitted by a Nd:YAG laser as the direction of the linearly polarized pump beam is changed. The accurate description of the emitted polarization state is an exciting topic encountered in many laser systems and often depends on the peculiarities of the laser structure. However, we expect that the behavior of our Nd:YAG laser will highlight key polarization properties of many Class B lasers which include semiconductor lasers. As we shall demonstrate experimentally, numerically, and analytically, the slow evolution of the inversion of population relative to the laser fields is responsible for unusual polarization switching properties.
