摘要： A programmable tailored laser pulse generator (10) including a pulsed seed laser source (12), a laser amplifier (20), and an optical power amplifier (30) produces high power tailored laser pulses (32) shaped in response to a programmable analog tailored pulse signal applied to a seed laser (first embodiment) or an external modulator of continuous-wave seed laser output (second embodiment). The programmable analog tailored pulse signal is generated by combining multiple individually programmable analog pulses generated by a multi-channel signal generator (18). A bias applied to the pulsed seed laser source generates pre-lasing prior to producing a tailored laser pulse so that the seed laser source spectral line and line width stabilize within a narrow gain line width of a solid-state laser amplifier, thereby to impart pulse peak stability of the laser output. The tailored laser pulse generator allows for generating harmonics at shorter wavelengths and provides an economical, reliable laser source for a variety of micromachining applications.
