江苏省激光研究所和南通县通海激光仪器厂合作,为美容激光治疗仪研制成自聚式CO_2激光器,并用于临床。所谓自聚式CO_2激光器,即在普通CO_2激光器的基础上,激光光束按照设计要求通过输出透镜自行聚焦或扩散。其原理如图所示。从图中可看出,把普通CO_2激光器的输出反射镜做成平一凸透镜,分别镀增反介质膜和增透介质膜,平面作为激光束的反射面,而凸面作为输出面。平一凸透镜的曲率半径,根据实际需要而定。用自聚式CO_2激光器装成的LT-Ⅰ型激光
Laser Institute of Jiangsu Province and Nantong Tonghai Laser Instrument Factory for the beauty laser treatment developed self-coherent CO 2 laser and used in clinical. The so-called self-converging CO_2 laser, that is, the ordinary CO_2 laser based on the design of the laser beam through the output lens self-focusing or diffusion. The principle as shown. Can be seen from the figure, the ordinary CO_2 laser output mirror made of flat convex lens, anti-dielectric film and antireflection coating antireflection film, the plane as the laser beam reflection surface, and the convex surface as the output surface. Flat-convex lens radius of curvature, according to actual needs. LT-Ⅰ type laser with self-assembled CO_2 laser
