Or example, sity, the nonlinear phase is accumulated, as well as the intensity I1 requires on a maximal worth, an input pulse of 50 fs might be shortened to 38 fs [10], which can be a tiny compression aspect. offered that B = , = , and R = 0.5. Consequently, the pulse emerging at this port The initial way to raise the compression aspect is always to use a CM to eliminate the chirp has a greater contrast. Moreover, the pulse duration shortened just after reflection from the in the pulse. It’s quick to show that the output pulse I1 accumulates a nonlinear phase CM. For instance, output pulse accumulates nonlinear phase B = [10], B2)/2. Where, Bout = /2 becausean input pulse of 50 fs could be shortened to 38 fs (B1 +which is really a tiny out compression element.

We employed Equation (three) for the numerical modeling of pulse propagation, each inside the interferometer’s beam splitters, and in thin plates. Equation (three) is solved numerically by the split step Fourier technique (SSFM). This system is widely used for solving the issue of pulse propagation in a nonlinear dispersive medi.
