1973年西德 Nath 等首先应用100～200nm石英光导纤维传导激光,在光导纤维两端拉成600nm 以提高导光率。Nath 用此光导纤维传导 A_r~+ 激光,用以烧灼狗肝获得成功。1975年 Reiclenbachs 报告应用柔软的硅胶包光导纤维于临床。同年 Frihm Rgen 及 Dwyer等报告用该光导纤维导 A_r~+ 激光治疗2例消
In 1973, Nath et al. in the United States first applied 100-200nm quartz optical fiber to conduct laser light, and pulled 600nm at both ends of the optical fiber to increase light transmittance. Nath used this fiber-guided A_r~+ laser to burn dog liver successfully. In 1975 Reiclenbachs reported the use of soft silica-coated optical fibers for clinical use. In the same year, Frihm Rgen and Dwyer reported using the fiber-guided A_r~+ laser to treat 2 cases.
