Continuous-wave diode-pumped laser action of Nd3+-doped photo-thermo-refractive glass
Abbreviated Journal Title
VOLUME BRAGG GRATINGS; YAG; Optics
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 124 mW, 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 3.5 nm shift of pump wavelength from its absorption center.
