Polarization coupling on dual-polarization generation in a pulsed nd:yag laser

Abstract

This paper considers coupling between two orthogonal polarizations generated simultaneously in a Nd:YAG laser. It is experimentally shown that such generation is possible if the difference between the loss factors for two polarizations is rather considerable. A simple method is proposed to equalize the losses for both polarizations and achieve the same average intensity. It is shown that a theory based on a point laser model cannot adequately describe such a generation, as it does not take into account the incomplete overlapping of the cavity modes which correspond to different polarizations.
