PROBLEM TO BE SOLVED: To provide a laser oscillator capable of performing easily the optical-axis adjustment of a Q-switch, and especially, perform easily the optical-axis adjustment of a Q-switch in an air-cooled laser oscillator. SOLUTION: The laser oscillator has a rear mirror 4 and an output mirror 7 which form together a resonator optical axis, a laser crystal 5 provided on the resonator optical axis and for performing the stimulated emission of a laser beam, an acoustic element 6 for controlling a laser oscillation by diffracting the laser beam present on the resonator optical axis, a resonator housing for storing the laser crystal and the acoustic element in a hermetic space, an exciting-light feeding portion for making an exciting light incident on the laser crystal, and an exciting-light-path adjusting portion for adjusting the incident path of the exciting light on the laser crystal. Further, the laser oscillator performs the optical-axis adjustment of a Q-switch by changing the incident path of the exciting light. COPYRIGHT: (C)2006,JPO&NCIPI
