一个3妈妈激光生成交付仪器，使用硫属纤维具有独特的损伤阈值和锥形辐射输入已开发用于医疗应用。提出了一种新的提纯和合成方案，可制得异相夹杂物含量小于10（4）cm（-3）的纤维。在这样的光纤中，在YAG：Er激光器中，在0.5 kW/cm（2）的平均功率密度下，损伤阈值为350 J/cm（2），该激光器工作在脉冲持续时间为350 ms的重复脉冲自由运行机制中。在输出功率降低15%的条件下，以3 Hz的重复频率和1 W的平均输出功率传输1-3 x 10（4）个激光脉冲。
A 3-mum laser-generation delivery instrument that uses chalcogenide fibers with a unique damage threshold and conical radiation input has been developed for medical applications. A new purification and synthesis scheme has been elaborated that yields fibers with a heterophase inclusion content of less than 10(4) cm(-3). In such fibers the damage threshold is 350 J/cm(2) at an average power density of 0.5 kW/cm(2) in a YAG:Er laser operating in the repetitive pulse free-running regime with a pulse duration of 350 ms. 1-3 x 10(4) laser pulses were transmitted at a repetition rate of 3 Hz and an average output power of 1 W under the condition of a 15% decrease in the output power.
