Abstract
A method for laser machining of material using a burst comprised of laser pulses. The method tailors the pulse width, pulse separation duration, wavelength and polarization of the multiple laser pulses included in a burst to maximize the positive effect of thermal and physical changes achieved by previous pulses that have impinged upon the machined material.
