Abstract
We report laser operation at 1.81 μm and 1.85 μm in a Tm/sup 3+/:LiNbO3 Ti-diffused waveguide doped by thermal indiffusion at high temperature. We believe this is the first time lasing has been seen in Tm:LiNbO3 at room temperature. Continuous-wave operation was achieved at room temperature with a threshold of 42 mW launched pump power. The output power was observed to be stable, without any sign of photorefractive damage.
