Abstract

We investigate the polarisation-mode dynamics and Lamb's mode coupling constant for orthogonally polarised laser states in a dual-mode (100)-cut Nd:YAG laser with feedback, and compare with an anisotropic rate equation model. The anisotropic (100)-cut Nd:YAG exhibits thermally-induced depolarisation and polarisation-mode coupling dependent on the pump polarisation, crystal angle and laser polarisation directions. Here, the links between the depolarisation and polarisationmode coupling are discussed with reference to a rate equation model which includes gain anisotropy in a quasi-isotropic laser cavity.
