High-Frequency Bragg Gratings In A Photothermorefractive Glass
Holographic UV mirrors were recorded in a volume of photothermorefractive glass. This photosensitive silicate glass doped with silver, cerium, and fluorine is transparent in the near-UV, visible, and near-IR spectral regions, and its induced refractive-index change reaches 10-3. UV radiation of a He-Cd laser at 325 nm was used for Bragg grating recording with a spatial frequency of ∼9200 mm-1. The absolute diffraction efficiency of the recorded mirror reached 12.6% at 325 nm and did not deteriorate under the long-time effects of optical irradiation and heating up 400°C. © 2000 Optical Society of America.
