Claim 0:
1. A laser system, comprises:
an integrated fiber laser front-end, configured to generate and output a pre-amplified first pulsed laser beam having predefined beam characteristics corresponding to a setting selection of a controller, wherein the predefined beam characteristics comprise: a beam frequency, a first energy, a pulse modulation frequency, a first spatial profile including a first beam diameter, and a pulse shape, and a first temporal profile including a pulse width PW1;
an optical filter configured to modify the pre-amplified first pulsed beam to output a second pulsed laser beam having a second spatial profile and a second energy; and
a multi-stage post-amplifier configured to output an output beam having the after beam energy post amplifications and beam profile modifications, the multi-stage post-amplifier comprising:
a first stage configured to post-amplify and modify the second pulsed laser beam to output a third pulsed laser beam having a third energy and a third temporal profile; and
a second stage configured to post-amplify and modify the third pulsed laser beam to output a fourth pulsed laser beam as the output beam having a fourth energy and a fourth temporal profile, wherein the fourth pulsed laser beam substantially maintains the pulse width setting PW1 within a defined tolerance of the setting selection.
