Title

Continuous-Wave Diode-Pumped Laser Action Of Nd3+-Doped Photo-Thermo-Refractive Glass

Abstract

Laser action of the photo-thermo-refractive (PTR) glass, which is the photosensitive material for holographic recording of volume Bragg gratings (VBGs), was demonstrated for the first time by introducing Nd3+. Nd:PTR glass has a bandwidth of 27:8nm and 16:0nm for luminescence and absorption, respectively. An uncoated 2mm thick Nd:PTR element generated cw laser output of 124mW, with a slope efficiency of 25%, by laser diode pumping. This Nd:PTR glass also performed wide bandwidth laser action at 1053:9-1063:3nm, where the decrease of the pump-absorption efficiency was held off below 30%, even under a 3:5nm shift of pump wavelength from its absorption center. © 2011 Optical Society of America.
