摘要： The invention relates to a method and apparatus for shaping a laser pulse. The method comprises the steps of generating a laser pulse with a laser, opening an optical switch to allow the laser pulse to pass through the optical switch, determining a first reference time point with respect to the laser pulse, determining a second reference time point with respect to the opening of the optical switch, and adjusting an opening time of the optical switch based on the first and second reference time points to shape the laser pulse. The method may be carried out with an apparatus which comprises a laser which generates the laser pulse, a first optical detector which detects the laser pulse and generates a first signal representing the laser pulse, an optical switch through which the laser pulse passes, a second optical detector which detects the laser pulse after the laser pulse has passed through the optical switch, and which generates a second signal representing the laser pulse, a computer which receives the first and second signals and which calculates a delay period based on the first and second signals, and a pulse generator which receives the delay period from the computer and which generates a pulse delayed by the delay period to open the optical switch.

摘要： An exemplary laser apparatus comprises an amplification medium which amplifies a coherent beam passing through the amplification medium, a pump which provides energy to the amplification medium, a tunnel having a first end proximate to the pump and a second end proximate to the amplification medium, wherein the energy provided by the pump passes through the tunnel en route to the amplification medium, and a moveable member for adjusting a spatial distribution of the energy provided to the amplification medium by the pump. The moveable member typically comprises a flat, reflecting strip or flap which redirects a portion of the energy of the pump beam to a peripheral region of the amplification medium. The angular and translational position of the flap is adjustable on line so that the pump distribution can be adjusted while the laser is running to reduce observed optical distortions caused by heating of the amplification medium.

摘要： A method for laser shock peening a target surface generates laser pulses from a cavity dumping oscillator having an optically-pumped laser and directs the pulses against the target. A first technique uses pulses having rectangular cross section. A second technique passes each generated pulse two or more times through the same optical amplifier before directing the pulse against the target. A third technique drives the laser with a time pulse of electric current having a rectangular shape. A reflective laser beam homogenizer uses two abutting mirrors to split a laser beam into two equal halves and then uses an odd number of additional mirrors to reflect each half first behind and then to the opposite one of the two mirrors to be reflected back as a beam having interchanged halves.

摘要： The invention relates to a method and apparatus for accurately measuring the energy of a laser pulse. The method according to one embodiment comprises directing a first laser pulse to an energy sensor which produces a first signal responsive to the first laser pulse, determining a time constant of the energy sensor based on the first signal, directing a second laser pulse to the energy sensor which produces a second signal responsive to the second laser pulse, and determining the pulse energy of the second laser pulse based on the second signal and the time constant. The method may be carried out with an apparatus which comprises an energy sensor which receives a laser beam and generates a signal responsive to the laser beam, a digitizer which digitizes the signal, and a computer which calculates a time constant of the energy detector based on the digitized signal of the first laser pulse incident on the energy detector and calculates an energy of a second laser pulse based on the digitized signal of the second laser pulse and the time constant. The method and apparatus provide accurate and timely energy measurements which can be used to improve the laser shock peening process.
