  • Patent number: 11858065
    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.

  • Publication number: 20230098272
    Abstract: An apparatus is provided, the apparatus comprising: (i) a diode-pumped solid-state laser oscillator configured to generate a pulsed laser beam having predefined beam characteristics corresponding to a current setting selection of a controller; and (ii) an amplifier configured to amplify an energy and modify a beam profile of the pulse laser beam. A beam detector is coupled to the generated beam to monitor a combination of: (i) a beam pulse width; (ii) a beam diameter; and (iii) an energy level, and generates an error signal to be sent back as a feedback signal to the controller. The controller configures the current source to output a correction current to tune the DPSSL oscillator, the wave plate, and the first polarizer to rotate a correction polarization angle and adjust the energy amplification or temporal profile to within a defined performance tolerance.
