ABSTRACT:
A solid-state laser system capable of generating a linearly polarized laser beam and achieving a high oscillation efficiency by suppressing an insertion loss to a minimum. A polarization control element is made of an angularly cut crystal having a birefringence, and the thickness and reflectivities of the end surfaces of the element are adjusted so that the control element can act as a Fabry-Perot etalon. This polarization control element is interposed between an end surface of an Nd:YAG crystal which acts as a solid-state laser medium and a resonator mirror.
