摘要： There is provided a passive Q-switch pulse laser device including a laser medium, and a saturable absorber. The laser medium is disposed between a pair of reflection means included in an optical resonator. The laser medium is excited by specific excitation light to emit emission light. The saturable absorber is disposed on an optical axis of the optical resonator and on a downstream side of the laser medium between the pair of reflection means. The saturable absorber has a transmittance increased by absorption of the emission light. At least one of the pair of reflection means is a polarizing element. The polarizing element has different reflectances with respect to the respective pieces of emission light in polarization directions orthogonal to each other.
