Ti:Er:LiNbO3 waveguide laser of optimized efficiency

The development of Fabry-Perot-type Ti:Er:LiNbO3 waveguide laser of optimized CW output power up to 63 mW (lambda(s) = 1561 nm) at a pump power level of 210 mW (lambda(p) = 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.
