Tunable coupled-cavity waveguide laser at room temperature in Nd-diffused Ti:LiNbO3

Record type: Article

We report on a Y-junction channel waveguide laser, operating at room temperature, in Nd-diffused Ti:LiNbO3. Pumping was performed with a cw Ti:Al2O3 laser operating at 816 nm. With feedback provided only by the polished end faces of the device, a cw lasing threshold of ~39-mW launched pump power was obtained, with a slope efficiency of ~35%. Using 95% reflectivity mirrors at the waveguide ends, we reduced the lasing threshold to ~4 mW, with a slope efficiency of ~2.6%. Tuning of the lasing signal over a range of 2.3 nm around a center wavelength of 1092.7 nm was demonstrated, with a monolithically integrated phase modulator.
