摘要	A conventional method for a solid-state laser device that obtains a laser beam output of a high quality at a high output using a laser diode as a pumping light source has a problem that the costs are increased and the fabrication becomes complicated due to an increasing number of components, such as a diffusing reflection mirror, a condenser lens, and a holding mechanism and a cooling mechanism thereof. Coating with a antireflection coating to reduce a transmission loss of laser diode light, and coating with a high reflection coating to reflect the laser diode light are provided alternately on the outer surface of a cooling tube. Also, an irradiation direction of the laser diode is not directed to the center of the laser rod, but is given with a certain angle to be positively tilted. This configuration makes it possible to eliminate the above problem.
其他摘要	使用激光二极管作为泵浦光源以高输出获得高质量激光束输出的固态激光器件的传统方法存在成本增加并且由于增加而使制造变得复杂的问题。多个部件，例如漫反射镜，聚光透镜，以及其保持机构和冷却机构。在冷却管的外表面上交替地提供涂有抗反射涂层以减少激光二极管光的传输损耗，以及用高反射涂层涂覆以反射激光二极管光。而且，激光二极管的照射方向不是指向激光棒的中心，而是以一定角度给出以使其正向倾斜。该配置使得可以消除上述问题。
