ABSTRACT
This work reports continuous laser action at room temperature in LiNbO[sub 3]:Nd[sup 3+] channel waveguides, fabricated by Zn diffusion. The absorbed pump power at the threshold was 1.25 mW and a slope efficiency of 20% was obtained. With our available pump power the laser could emit up to 0.14 mW without exhibiting any photorefractive damage. © 2001 American Institute of Physics. [DOI: 10.1063/1.1427426].
