We report on a Y-junction channel waveguide laser, operating at room temperature, in Nd-diffused Ti:LiNbO[sub 3]. Pumping was performed with a cw Ti:Al[sub 2]O[sub 3] laser operating at 816 nm. With feedback provided only by the polished end faces of the device, a cw lasing threshold of [similar to] 39-mW launched pump power was obtained, with a slope efficiency of [similar to] 35%. Using 95% reflectivity mirrors at the waveguide ends, we reduced the lasing threshold to [similar to] 4 mW, with a slope efficiency of [similar to] 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.
