Webtransform limited Gaussian pulse where the spectrum below 794 nm has been clipped. This clipping can occur, for example, if the stretcher or compressor of a chirped pulse … Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level, with the laser pulse being stretched out temporally and spectrally, then amplified, and then compressed again. The stretching and compression uses devices that ensure that the different color components of the pulse travel different distances.
