Abstract: Systems and methods generate laser pulse trains for material processing. In one embodiment, stable laser pulse trains at high repetition rates are generated from a continuous wave (CW) or quasi-CW laser beams. One or more laser pulses in the laser pulse train may be shaped to control energy delivered to a target material. In another embodiment, multiple laser beams are distributed to multiple processing heads from a single laser pulse, CW laser beam, or quasi-CW laser beam. In one such embodiment, a single optical deflector distributes multiple laser beams among respective processing heads.
