卤化银多晶光纤[AgCl_xBr_(1-x),0≤X≤1]是一种性能优良的中红外传能光纤。光纤原料采用高真空熔炼、氯气气氛下区域融熔和高真空石英安瓿内单晶生长等特殊工艺方法提纯,光纤用热挤压法成型。已制成的直径Φ1.0(mm)光纤L=1.64(m)输出CO_2激光功率>20(W),损耗0 3～0.5dB/m,Forurier红外光谱(FTIR)测量结果显示,光纤在4～16μm波段内有良好的透过率。用光纤制成的光纤式CO_2激光传输系统(光纤式CO_2激光手术刀),光纤手术刀长度L=1.3～1.8(m),输出功率>10～15(W),配有普通型和腔内专用型两种结构的输出端头。
Silver halide polycrystalline fiber [AgCl_xBr_ (1-x), 0≤X≤1] is a kind of middle-infrared fiber with excellent performance. The optical fiber raw materials are purified by special techniques such as high vacuum smelting, zone melting in a chlorine atmosphere and single crystal growth in a high-vacuum quartz ampoule, and the optical fiber is molded by a hot extrusion method. The results of Forurier infrared spectroscopy (FTIR) measurements show that the optical fiber has a diameter of 4 mm and a diameter of 4 mm. Optical fiber has a diameter of Φ1.0 mm. L = 1.64 (m) Output power of CO_2 laser> 20 W, loss of 0.3-3.5 dB / ~ 16μm band has a good transmittance. Optical fiber CO_2 laser transmission system (optical fiber CO_2 laser scalpel) made of optical fiber, the length of optical fiber scalpel L = 1.3 ~ 1.8 (m), output power> 10 ~ 15 (W), with a common type and cavity Dedicated two structure of the output terminal.
