Title

High Power High Brightness Volume Bragg Semiconductor Lasers

Abstract

While semiconductor lasers are the most efficient high power sources of optical radiation, their wide and unstable emission spectra and high divergence of radiation impede their utilization in a number of important industrial, medical, military, and scientific applications. One of the widely studied approaches to improve brightness of semiconductor lasers is the use of external resonators that provide spectral or angular mode selection. The most successful approach that was demonstrated during last ten years is the use of volume Bragg gratings (VBGs) recorded in photo-thermo-refractive (PTR) glass for spectral and angular selection in semiconductor laser resonators along with coherent and spectral beam combining. This paper describes increasing brightness of different types of single emitters and multichannel laser systems enabled by achievements in development of low absorption PTR glass and high optical quality of VBGs. © 2012 IEEE.
