Abstract

The spatial-mode characteristics are studied for a three-mirror resonator consisting of a diffractive aspheric third mirror aligned collinearly with a standing-wave two-mirror resonator. Simulations predict that enhanced spatial-mode selection and mode shaping can be achieved by this three-mirror cavity. A three-mirror Nd:YVO₄ solid-state laser with an optimized aspheric third mirror has been designed and implemented to oscillate in a designed fundamental Gaussian mode. The modal discrimination was measured to be 1.43 and the propagation factor M² was 1.02.
