The clinical use of a fiber-laser device based on continuous 250-W YAG-Nd laser allows the pathological tissue to be treated by exposure in various energy regimens, from its coagulation to intensive evaporation; the conditions of treatment created in this case for the patient are more comfortable than those with the use of less powerful laser devices. The elaboration and manufacturing of a new design for guiding the beam into a fiber wave guide with a light-guiding lead of 600 and more microns in accordance with the model of the used endoscope even without gas injection ensures reliable functioning of the fiber-laser device. Overheating of the in put and out put ends of the fiber wave guide in exploitation at large power regimens is excluded despite soiling of the distal end of the wave guide which is inevitable during the operation.
基于连续250瓦钇铝石榴石-钕（YAG-Nd）激光的光纤激光设备的临床应用，能够通过各种能量方案对病理组织进行治疗，从凝固到强烈蒸发；在这种情况下为患者创造的治疗条件比使用功率较小的激光设备时更为舒适。根据所用内窥镜的型号，精心设计并制造一种新的光束引导装置，将光束导入光导长度为600微米及以上的光纤波导，即使不注入气体，也能确保光纤激光设备可靠运行。尽管在操作过程中波导远端不可避免地会被弄脏，但在高功率方案下使用时，光纤波导的输入端和输出端不会出现过热现象。
