研究了不同波长范围为1 ~ 10μm的激光源对两种硫族玻璃红外光纤的透射特性。研究了芯径分别为250、500、750、1000μm和250、750、1000μm的As-Se-Te和As2S3glass纤维。衰减测量作为激光能量输入的函数和曲率的函数得到，只要这是可能的。利用光束轮廓仪对输出光束质量进行了研究。所使用的激光器分别是发射波长为1.06μm的调q Nd:YAG激光器、发射波长为2.94μm的自由运行或调q Er:YAG激光器和发射波长为9.3 ~ 10.6μm的可调谐脉冲co2激光器。当用Er:YAG激光器测试时，纤维表现出更好的性能，但在Nd:YAG和co2激光器的脉冲辐射下，它们被发现是脆弱的。输出光束分布总体上呈中心多尖峰能量分布。
Two different kinds of chalcogenide glass IR fibers were evaluated relative to transmission of pulsed IR radiation produced by several laser sources in the wavelength range from 1 to 10μm. Fibers composed either from As–Se–Te or from As2S3glass, of 250, 500, 750 and 1000μm and 250, 750 and 1000μm core diameters were studied, respectively. Attenuation measurements were obtained as a function of the laser energy input and as a function of curvature, wherever this was possible. The output beam quality was also studied using a beam profiler. The lasers used were a Q-switched Nd:YAG laser, emitting at 1.06μm, a free-running or Q-switched Er:YAG laser emitting at 2.94μm and a tunable pulsed CO2laser emitting in the range of 9.3–10.6μm. The fibers exhibited better behavior when tested with the Er:YAG laser and they were found fragile in pulsed radiation from the Nd:YAG and the CO2laser. The output beam profiles generally showed a central multi-spiking energy distribution.
