摘要： 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.

摘要： An apparatus may include a diode-pumped solid-state laser oscillator configured to output a pulsed laser beam, a modulator configured to modify an energy and a temporal profile of the pulsed laser beam, and an amplifier configured to amplify an energy of the pulse laser beam. A modified and amplified beam to laser peen a target part may have an energy of about 5 J to about 10 J, an average power (defined as energy (J)×frequency (Hz)) of from about 25 W to about 200 W, with a flattop beam uniformity of less than about 0.2. The diode-pumped solid-state oscillator may be configured to output a beam having both a single longitudinal mode and a single transverse mode, and to produce and output beams at a frequency of about 20 Hz.

摘要： An apparatus for directing a laser beam to a workpiece surface includes a housing having a laser beam exit aperture. The apparatus further includes an output optical device configured to emit a converging laser beam. The converging laser beam is centered on an axis and is directed outward from the housing through the exit aperture toward a workpiece surface. A water nozzle outlet is arranged to discharge a stream of overlay water toward the workpiece surface. An air nozzle outlet is arranged to discharge a stream of air in a direction transverse to the axis at a location axially between the water nozzle and the exit aperture.
