Abstract

The transverse-mode profiles for a plano–concave Nd:YVO4 microchip laser near threshold are examined, both experimentally and theoretically, and in both the near and the far field. We study in particular the transition from dominant quadratic index guiding to dominant gain guiding. The modal profiles change dramatically in this transition, and the agreement between experiment and the theoretical model is excellent.
