ABSTRACT:
A pulse compressor compresses a relatively long width optical pulse (of the kind which may be transform limited) to a short width pulse. The compressor includes a color generator which broadens the bandwidth of the long pulse to include any additional colors required for compression to the short pulse. The compressor also includes a grating which has a groove spacing and which is aligned with the output of the color generator at a grazing incidence angle effective for producing a compact grating structure, reduced ellipticity of the beam output from the compressor and high efficiency of light transmission through the device.
