とを特徴とするモード同期レーザ装置。 In a mode-locked laser device in which a laser resonator containing a continuously pumped solid-state laser is acousto-optically mode-locked and oscillated by a mode-locked modulator, a temperature controller adjusts the temperature of the mode-locked modulator to a set temperature. A mode-locked laser device, characterized in that the temperature is controlled by the temperature controller, and the ultrasonic resonance frequency of the mode-locked modulator is made to match the mode spacing frequency of the laser resonator, thereby enabling stable mode-locked oscillation. .
