Abstract: A micromachining system includes a laser generator, an acousto-optical deflector (AOD), and at least one signal generator. The laser generator is configured to generate a laser beam, and the at least one AOD is positioned in a path of the laser beam. The at least one acoustic signal generator is configured to generate at least two acoustic signals, including a first acoustic signal having a periodic waveform and a second acoustic signal having a freeform waveform. The at least one acoustic signal generator is further configured to apply the first acoustic signal to the AOD to output a deflected laser beam having a Gaussian profile, and apply the second acoustic signal to the AOD to adjust the Gaussian profile of the deflected laser beam to a modified profile.

Abstract: An optical system having coherence reduction capabilities includes a light source for generating a first light pulse; an asymmetrical pulse stretcher arranged to receive the first light pulse and to generate multiple light pulses, during a pulse sequence generation period, wherein the asymmetrical pulse stretcher includes multiple optical components which define a loop and a condenser lens is located between the asymmetrical pulse stretcher and an object, for directing the multiple pulses toward an area on the object At least two optical components of the multiple optical components are positioned in an almost symmetrical manner in relation to each other and introduce a coherence-related difference between at least two pulses of the multiple pulses. The pulse sequence generation period does not exceed a response period of a detector.
