Q-switched operation of a Ti:Er:LiNbO3 waveguide laser has been achieved wi
th up to 2.4 W pulse peak power (0.18 mu J) at 2 kHz repetition frequency w
ith an intracavity Mach-Zehnder-type amplitude modulator. A theoretical mod
el has been developed to describe the laser operation. Good agreement betwe
en numerical and experimental results has been achieved. Significant potent
ial for improvement is predicted.
