Flexible hollow glass waveguides with bore diameters as small as 250 µm have been developed for 3-µm laser delivery. All the guides exhibit straight losses between 0.10 and 1.73 dB/m, and the loss increases to between 2.4 and 5.1 dB/m upon bending 1 m of the guides into 15-cm-diameter coils. This behavior is shown to depend strongly on the launch conditions and mode quality of the input beam. The waveguides are capable of efficiently delivering up to 8 W of Er:YAG laser power with proper input coupling, and they are suitable for use in both medical and industrial applications.
已经开发出内径小至250微米的柔性中空玻璃波导用于3微米激光传输。所有波导的直线损耗在0.10至1.73分贝/米之间，当将1米长的波导弯曲成直径15厘米的线圈时，损耗增加到2.4至5.1分贝/米之间。结果表明，这种行为强烈依赖于输入光束的发射条件和模式质量。这些波导在适当的输入耦合下能够有效地传输高达8瓦的铒：钇铝石榴石激光功率，适用于医疗和工业应用。
