  • Non-fourier pulse-shapers including a combined pulse-shaper and pulse-compressor
    Patent number: 7688493
    Abstract: A pulse-shaper for temporally shaping an optical pulse includes a prism or a grism arranged to disperse the optical pulse into a diverging fan of spectral-component rays. The fan of spectral-component rays is collimated by a lens or another grism. The collimated spectral-component rays are selectively modulated by a spatial-light-modulator (SLM). The modulated rays from the SLM are either recombined to form the temporally shaped pulse by another lens and another prism, another two grisms, or by the same lens and prism or the same two grisms.
