Abstract
A laser system includes 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 user defined pulse shape and a user defined pulse width setting selection of a controller. The first pulsed laser beam is generated from a master oscillator which outputs a CW laser beam to a temporal pulse shaper, which modulates the CW laser beam to output the first pulsed laser beam in response to an electrical pulse from an arbitrary wave generator and a DC bias voltage from an automatic modulator bias control circuitry. The first pulsed laser beam is pre-amplified to an output pulsed laser beam for laser peening or laser bond inspection. A beam detector is used to monitor beam characteristics, and to generate an error signal to be sent back as a feedback signal to the controller for adjustments and corrections.
