DBR and DFB lasers in neodymium- and ytterbium-doped photothermorefractive glasses

Opt Lett. 2014 Apr 1;39(7):2156-9. doi: 10.1364/OL.39.002156.

Abstract

The first demonstration, to the best of our knowledge, of distributed Bragg reflector (DBR) and monolithic distributed feedback (DFB) lasers in photothermorefractive glass doped with rare-earth ions is reported. The lasers were produced by incorporation of the volume Bragg gratings into the laser gain elements. A monolithic single-frequency solid-state laser with a linewidth of 250 kHz and output power of 150 mW at 1066 nm is demonstrated.
