Abstract

We have demonstrated an Nd:glass waveguide laser deposited on a silica substrate by flame hydrolysis deposition using chelates. Continuous-wave lasing at λ = 1062 nm was verified with a threshold of 143 mW and a slope efficiency of 2.1% when the laser was pumped at 807 nm. The flame hydrolysis deposition process using rare-earth chelates produces low-loss films with high Nd concentration and is suitable for multiple rare-earth doping.
