Abstract: In a solid-state laser device which emits an output laser beam by pumping a solid-state laser medium in a laser resonator by an excitation laser beam generated from a semiconductor laser unit, both the solid-state laser medium and the laser resonator are mounted on a common thermal conductive support which is thermally controlled by a temperature controller through a Peltier effect element to keep a temperature of the thermal conductive support substantially constant. A thermistor is attached to the thermal conductive support to detect the temperature of the support and to supply the temperature controller with a temperature detection signal representative of the temperature of the support. The temperature controller carries out proportional-plus-integral-plus-derivative control to supply a control signal to the Peltier effect element.

Abstract: In a solid-state laser device which pumps a solid-state laser medium in a laser resonator by an excitation laser beam generated from a semiconductor laser unit and which emits an output laser beam, a photo detector detects intensity of the output laser beam to produce a photo detection signal which corresponds to the intensity of the output laser beam and which is sent to a controller. The controller controls the semiconductor laser unit in response to the photo detection signal and adjusts intensity of the excitation laser beam to keep the intensity of the output laser beam substantially constant. The solid-state laser medium may be pumped from an end surface or a side surface. An optical function element, such as a wavelength conversion element, a Q switch element, may be located outside or inside of the laser resonator.
