Abstract :
Volume Bragg gratings (VBG) with efficiency exceeding 95% recorded in a novel patented material, which is a photo-thermo-refractive (PTR) glass, and used for high-power laser beam control. Exceptionally narrow spectral and/or angular selectivity are used for angular magnification in laser scanners, spectral beam combining, and spectral stabilization of semiconductor lasers.
