Abstract
A device for linearly extending the duration of laser light pulses by subjecting the pulses to double diffraction based on a series of variable step gratings placed at right angles to each other. Increased power density is obtained by placing a compression grating at an angle such that each wavelength of light emerging from the compression grating travels an optical path of approximately the same distance, and focusing the emerging light with a lens. Increased amplification is obtained by placing a segmented laser amplifier, one segment aligned with each wavelength of light separated by the double diffraction of the series of variable step gratings and interposed between the series of variable step gratings and the compression grating.
