Abstract
A solid state laser includes a resonator, a solid laser crystal disposed in the resonator, a pumping source for pumping the laser crystal, a pair of .lambda./4 plates which is disposed in the resonator with the laser crystal intervening therebetween and makes an oscillation beam of a twisted mode, and a polarization control element which is disposed in the resonator and sets the linear polarization of the solid state laser beam in a predetermined direction. The solid laser crystal is a birefringent crystal and an optical axis of the birefringence of the solid laser crystal is oriented in the direction of the linear polarization of the solid state laser beam set by the polarization control element.
