ABSTRACT:
There is disclosed a solid-state laser resonator capable of outputting a high power linearly polarized laser beam, in which a laser beam subjected to the birefringence in the laser resonator is effected to minimize a component of the laser beam which is orthogonal with the direction of polarization definable by a Brewster plate upon traversing a quarter-wave plate, to enable the linear polarization output distribution of the laser beam to become uniform. With this, the emission efficiency and the output power of a linearly polarized laser beam are much improved.
