<p>A system for generating a pulsed laser beam includes a laser source (12) and a mode locker (32) which are mounted in a housing that defines a beam path (22) for light from the laser source. An electro-optical crystal (24) is positioned on the beam path to selectively polarize light travelling along the beam path. In operation, the crystal is repetitively advanced through a three period working cycle. At the beginnig of the no-laser period which initiates each working cycle, the electro-optical crystal (24) is partially activated.</p> |
