Shank, "Compression of Optical Pulses Chirped by Self-Phase Modulation in Fibers," Optical Society of America Vol. The problem of generating ultrashort optical pulses is, in general, one of minimizing phase distortion. The well-resolved interference maxima also provide a rigorous calibration of the relative delay. For the material other than that in the prisms we use SF11, which is used in microscope objectives and dominates the material dispersion. The problem of generating ultrashort optical pulses is, in general, one of minimizing phase distortion.affect the pulse in temporal domain. Compression of positively chirped pulses also happens in negative dispersion (anomalous) regime [5]. So replacement of bulk diffraction grating in compressor part can be possible if the desired compression of pulse obtained by controlling the pulse as well as the optical fiber parameters.

Econ Circle, Oviedo, Florida bUniversity of Central Florida, . The development of phased-array grating compressor is a crucial issue for high-energy, ultra-short pulse petawatt-class lasers. We present a theoretical and experimental analysis of two-grating phasing in a broadband pulse mosaic compressor. The phase defaults induced by misaligned gratings are studied. Monochromatic grating phasing is experimentally achieved with an interferometric technique. Treacy has shown that a pair of diffraction gratings can be used to compensate for the quadratic phase distortion, (d 2 4/dW 2) 0,,o of a frequency-broadened optical pulse. 5 He also pointed out in the same paper that the principal remaining problem in pulse compression of large-bandwidth signals using gratings is uncompensated cubic phase distortion, (d 3 0/dw 3)w 0.
