Abstract :
We report the design and characterization of a novel Q-switched laser configuration based on a composite Er/sup +3/-Yb/sup +3/ co-doped ion-exchanged glass and Ti-indiffused LiNbO3 waveguides. This 1536 nm Q-switched laser provides stable 200 ns wide optical pulses for a cavity length of 7 m with a peak power of 13.5 W and a pulse energy of 2.7 μJ at a 2-kHz repetition rate and 180 mW of 980-nm pump power. Also, we examine the dependence of the pulsewidth and peak power on the laser cavity length to estimate the performance of the integrated version of such a laser.
