Linear angular dispersion compensation of cleaned self-diffraction light with a single prism

The linear angular dispersion of a self-diffraction (SD) pulse, from a femtosecond laser pulse cleaning device, is compensated for by the use of a single prism. More than 500~[STIX]x03BCJ first-order SD pulse has a contrast of 10¹² , which is about five orders of magnitude improvement from the input fundamental pulse. The wings of the distribution away from the main pulse in ± 1 ps are cleaned with a contrast improvement of about 10⁷ , which verifies the pulse cleaning ability of the SD process.
