Fabrication of 75-μm-bore hollow optical fibers for infrared transmission

Autor: Yi-Wei Shi, Yasuhiro Sasaki, Mitsunobu Miyagi, Xiaosong Zhu, Yuji Matsuura, Hiroyuki Takaku, Katsumasa Iwai

Publikováno v: Optical Fibers and Sensors for Medical Diagnostics and Treatment Applications XIX.

Extremely flexible hollow optical fibers with 75-μm-bore size were developed for infrared laser light delivery. The hollow fiber was inner coated with silver and dielectric layers to enhance the reflection rate at an objective wavelength band. The s
