本文研究了高功率激光束通过国产的低损耗光纤的耦合-传输特性。已研制成由透镜-光纤-透镜组成的光纤光缆。通过2米长的石英光纤光缆已能输出200W的激光光束,其辐合-传输效率达90%。到目前为止,已成功地使用光纤光缆进行了六例肝癌手术、一例肝血管瘤手术和一例口腔癌手术。

The coupling-transmission characteristics of high power laser beam through a low-loss optical fiber made in China are investigated. The fiber optic cable composed of lens-fiber-lens is developed. 200 watt output power and 90% coupling-transmission efficiency are obtained by using the quartz fiber cable with 2m length. Up to now the fiber optic cable is successfully applied to the treatment of six cases of hepatic cancer, one case of hepatic blood vessel tumour and one case of oral cavity cancer.
