Effect of delayed nonlinear response on femtosecond optical pulse compression by use of an organic crystal-cored fiber in the normal dispersion region.
We investigate the effect of delayed nonlinear response time on pulse compression, using an organic crystal-cored fiber in the normal dispersion region. With up to third-order phase compensation, a 100-W, 100-fs hyperbolic-secant pulse is compressed to ~10 fs with a delayed nonlinear response time as well as without it. It is shown that third-order phase adjustment can compensate for the phase asymmetry in the frequency domain that is induced by the effect of the delayed nonlinear response.
