摘要： A target is laser shock peened by directing against an ablative coating thereon a laser beam pulse having a fluence, duration, and corresponding peak power effective for ablating the coating to form a plasma and shock wave therein. The plasma is confined adjacent the target to plastically deform the target by the shock wave to develop residual compressive stress therein. The pulse has a duration less than ten nanoseconds and a corresponding peak power for increasing coupling efficiency between the pulse and plasma.

摘要： An optical modulator includes pump and signal lasers optically aligned with an optical modulator element having a nonlinear refractive index. In operation, a pulsed optical pump beam is focused inside the modulator element for obtaining oscillatory sagittal and tangential mode radii thereof. A signal beam is propagated through the focus in the modulator element at a crossing angle with the spatially modulated pump beam for phase modulation thereof. Material nonlinearity due to electronic polarization or molecular orientation provides ultrafast rise times with correspondingly high modulation bandwidth.

摘要： A method of controlling the size of a laser beam comprises the steps of generating the laser beam with a laser, focusing the laser beam, directing the laser beam to a target, directing a portion of the laser beam to an optical detector which generates a signal representative of a fluence distribution of the laser beam, and adjusting a focal point of the laser beam based on the measured fluence distribution to control the size of the laser beam on the target. The method can be carried out with an apparatus which comprises a beam splitter which divides the laser beam into a first portion and a second portion, a lens which focuses the first portion of the laser beam for incidence on a target, a detector which receives the second portion of the laser beam and which generates a signal representative of a spatial energy distribution of the laser beam, a digitizer which digitizes the signal from the detector, a data analyzer which receives the digitized signal from the digitizer and which calculates a fluence distribution of the laser beam, and a lens controller for adjusting a position of the lens with respect to the target based on the fluence distribution.

摘要： A laser resonator includes a laser medium having opposite end faces inclined at Brewster's angle and disposed in optical alignment between spaced-apart and tilted first and second optical elements. A method for adjusting the optical alignment includes pumping the laser medium to produce a laser beam, and adjusting separation spacing between the two optical elements. Tilt of at least one of the optical elements is adjusted in response to any observed change in beam cross-sectional size. In an additional embodiment, the laser medium is initially positioned at about equal spacings between the first and second elements. Position of the laser medium is then adjusted, at a constant value of the separation spacing, to within a position range selected for a specific value of a ratio of intracavity peak power of circulation of the laser beam and a critical power for self-focusing to effect discrimination of mode-locked operation over continuous wave operation.
