Investigations on transfer of the novel diode pumped Er:YAG laser radiation by special hollow glass waveguide

Popis výsledku v původním jazyce

Delivery of flashlamp pumped Er:YAG laser radiation (lambda = 2.94.m) 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 mu m. 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 degrees with a bending radius of 15 cm. The output beam spatial structure was not changed for investigated bending angles 0 degrees, 45 degrees, 90 degrees, and 180 degrees (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.
