摘要:
An object of the invention is to provide a solid state laser device design so as to improve a cooling effect in said laser device; whereby an electric power to be applied to an excitation lamp can be increased, a large oscillation power can be obtained, and a thermal lens effect generated in the laser medium can be suppressed. The solid-state laser device includes a laser medium, an excitation lamp for applying excitation light to the laser medium, a transparent first cooling pipe accommodating the laser medium, a transparent second cooling pipe accommodating the excitation lamp, wherein a first cooling system which feeds a cooling water to the first cooling pipe and a second cooling system which feeds a cooling water to the second cooling pipe are independent of each other and the respective systems have a water-feeding pump. The cooling pipes are formed of cerium-doped quartz glass capable of inhibiting transmission of light having a wavelength not longer than 320 nm.
