Abstract
Hollow fibers for variety of lasers emitting wavelengths from the infrared to ultraviolet are introduced. Forinfrared lasers represented by CO2 and Er: YAG lasers, hollow fibers having dielectric and silver film on theinside of glass tubing have been developed. It is shown that the fibers transmit high-powered laser light withlow attenuation due to the interference effect of the internal dielectric layer. For excimer laser light, hollow glassfibers with an inner aluminum film show low loss characteristics because of the high reflection coefficient ofaluminum in the ultraviolet region. Hollow fibers enable many applications in industrial and medical fieldsthat need effective delivery medium of laser light.
