Non-photorefractive cw Tm-indiffused Ti:LiNbO3 waveguide laser operating at room temperature
IEEE Photonics Technology Letters, 8, (2), . (doi:10.1109/68.484243).
We report laser operation at 1.81µm and 1.85µm in a Tm3+: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 absorbed power. The output power was observed to be stable, without any sign of photorefractive damage.
