Single polarized Tm 3 + laser in Zn-diffused Li Nb O 3 channel waveguides
In this work, laser operation at 1.76 μ m in Tm 3 + : Li Nb O 3 Zn-diffused channel waveguides is reported. The laser emission is single polarized with the electric field parallel to the optic axis ( π -polarization) and operates in continuous-wave regime, at room temperature. The threshold of laser...

Zn-diffused channel waveguides is reported. The laser emission is single polarized with the electric field parallel to the optic axis
(
π
-polarization) and operates in continuous-wave regime, at room temperature. The threshold of laser oscillation is in the range of
40
mW
, the slope efficiency is around 1%, and both magnitudes are dependent on the channel width, in accordance with the mode overlap between the pump and signal modes within the waveguides. |
