Abstract :
The development of a Fabry-Perot-type Ti,Er:LiNbO3 waveguide laser of optimized CW output power up to 63 mW (λs =1561 nm) at a pump power level of 210 mW (λp=1480 nm) and a slope efficiency of up to 37% is reported. The theoretical model for the waveguide laser is presented and applied to determine the optimum resonator configuration using waveguide parameters obtained from a detailed characterization of the laser sample. With pulsed pumping, waveguide laser pulses of up to 6.2 W peak power were observed. Apart from residual relaxation oscillations, the laser emission proved to be shot-noise limited
