引言最近,在医学领域中利用聚焦在微小点上的高能量激光,开拓了细胞外科、激光发光光谱分析法等领域,利用激光束所具有的特殊效应而制成的光凝固装置(用于治疗视网膜剥离),以及激光对癌的破坏效应等正在进行研究。现在,在医学领域中使用的器件是固体激光器 INTRODUCTION Recently, the use of high-energy laser light focused on tiny spots in the field of medicine has opened up photocoagulation devices using the special effects of laser beams in the fields of cell surgery, laser emission spectrometry and the like Retinal detachment), as well as the damaging effects of laser on cancer and the like. Devices used in the medical field are now solid-state lasers
