摘要：A programmable tailored laser pulse generator including a pulsed seed lasersource, a laser amplifier, and an optical power amplifier produces high power tailored
laser pulses shaped in response to a programmable analog tailored pulse signal appliedto a seed laser (first embodiment) or an external modulator of continuous-wave seedlaser output (second embodiment). The programmable analog tailored pulse signal isgenerated by combining multiple individually programmable analog pulses generated bya multi-channel signal generator. A bias applied to the pulsed seed laser sourcegenerates pre-lasing prior to producing a tailored laser pulse so that the seed lasersource spectral line and line width stabilize within a narrow gain line width of a solid-statelaser amplifier, thereby to impart pulse peak stability of the laser output. The tailoredlaser pulse generator allows for generating harmonics at shorter wavelengths andprovides an economical, reliable laser source for a variety of micromachining applications.
