With a 2% output coupler at this wavelength a laser threshold of 17mW and a 20% slope efficiency were obtained. This demonstration of low propagation loss combined with the fact that these waveguides have a very high numerical aperture, make pulsed laser deposited thin films attractive for high power diode pumped devices.

Abstract

We report the laser performance of a low propagation loss neodymium doped Gd3Ga5O12 (Nd:GGG) waveguide fabricated by pulsed laser deposition. An 8µm thick crystalline Nd:GGG film grown on an undoped Y3Al5O12 (YAG) substrate lases at 1.060µm and 1.062µm, when pumped by a Ti:sapphire laser operating at 740nm or 808nm. Using a 2.2% output coupler a 1060nm laser threshold of 4mW and a slope efficiency of 20% were observed. Laser action has also been achieved, we believe for the first time in Nd:GGG, on the quasi-three level 937nm transition. With a 2% output coupler at this wavelength a laser threshold of 17mW and a 20% slope efficiency were obtained. This demonstration of low propagation loss combined with the fact that these waveguides have a very high numerical aperture, make pulsed laser deposited thin films attractive for high power diode pumped devices.
