Abstract
A laser system for processing a workpiece includes a tunable pulsed laser source having an output comprising a set of optical pulses. The tunable pulsed laser source includes a seed source, an optical circulator having a first port coupled to the seed source, a second port, and a third port, a modulator driver, and an amplitude modulator coupled to the modulator driver. The tunable pulsed laser source also includes a first optical amplifier characterized by an input end and a reflective end and a second optical amplifier coupled to the third port of the optical circulator. The laser system also includes a controller configured to adjust laser parameters of the tunable pulsed laser source, a supporting member configured to support the workpiece, and an optical system configured to adjust laser beams from the tunable pulsed laser source and direct them towards the workpiece.
