| 英文摘要 | A laser device includes a surface emitting laser array, a first light condensing optical system, an optical fiber, a second light condensing optical system, and a laser cavity. The light from the surface emitting laser array enters the laser cavity via the first light condensing optical system, the optical fiber, and the second light condensing optical system. The laser cavity is a Q-switched laser and includes a laser medium and a saturable absorber. A beam waist diameter r of the light (excitation light) that irradiates the laser cavity, is set so that the beam waist diameter r and an initial transmittance T0 of the saturable absorber satisfy a relationship of 7.75×T04-7.77×T03+3.13×T02+0.16×T0+0.74≤r≤2.62×T0+0.675. |
