Method and system for a pulsed laser source emitting shaped optical waveforms

A method of laser processing, the method comprising:

• outputting a first set of optical pulses from a tunable pulsed laser source toward a workpiece, wherein the workpiece comprises at least a first layer of a first material and a second layer of a second material, the first material being different from the second material, wherein the tunable pulsed laser source comprises:
• a seed source adapted to generate a seed signal;
• an optical circulator having a first port coupled to the seed source, a second port, and a third port;
• a modulator driver adapted to produce an electrical waveform;
• an amplitude modulator coupled to the modulator driver and adapted to receive the electrical waveform, wherein the amplitude modulator is characterized by a first side coupled to the second port of the optical circulator and a second side;
• a first optical amplifier characterized by an input end and a reflective end, wherein the input end is coupled to the second side of the amplitude modulator;
• and
• a second optical amplifier coupled to the third port of the optical circulator;
• processing the first layer using the first set of optical pulses;
• outputting a second set of optical pulses from the tunable pulsed laser source toward the workpiece, wherein the second set of optical pulses is different from the first set of optical pulses;
• and
• processing the second layer using the second set of optical pulses.
