闪光灯泵浦的Er：YAG激光（λ = 2.94 μm）通过空心波导传输是众所周知的。本研究的目的是研究一种新型的二极管泵浦的Er：YAG激光器与中空玻璃波导的连接的潜力，并设计一种新的中红外辐射传输的可能性。预期的用途是在医学上，因此需要一个足够灵活和无损的输送系统。传输系统的基础是一个特殊的环烯烃聚合物涂层银（COP/Ag）的空心玻璃波导。波导的长度为2.15 m，内径为700 μm。研究了波导弯曲角度对透射率的影响以及输出光束的空间分布。当光纤弯曲半径为15 cm，弯曲角度为180°时，透射率下降到79%。对于研究的弯曲角度0°、45°、90°和180°（弯曲半径为15 cm），输出光束空间结构没有改变。这些传输值预先确定了特殊空心玻璃波导与新型二极管泵浦Er：YAG激光器的结合使用，以进行进一步研究并随后用于医学。
Delivery of flashlamp pumped Er:YAG laser radiation (λ = 2.94 μm) by a hollow waveguide is quite well known. The goal of this study was to investigate the potential of connection of a novel diode pumped Er:YAG laser with a hollow glass waveguide and to design a new possibility for mid-IR radiation transfer. The expected use would be in medicine and therefore a sufficiently flexible and lossless delivery system is required. The base of transfer system was a special cyclic olefin polymer-coated silver (COP/Ag) hollow glass waveguide. The length of the waveguide was 2.15 m and inner diameter 700 μm. Transmission as a function of the input laser power and spatial distributions of the output beams were investigated depending on bending angle of waveguide. The transmission in the straight configuration were 89 % and decreased to 79 % when the fiber was bent to an angle of 180° with a bending radius of 15 cm. The output beam spatial structure was not changed for investigated bending angles 0°, 45°, 90°, and 180° (bending radius of 15 cm). These transmission values predetermine the use of the special hollow glass waveguides in conjunction with the novel diode pumped Er:YAG laser for further research with subsequent use in medicine.
