By solving a modified nonlinear Schrodinger equation considering the fifth-order susceptibility, we found that self-compression appeared even in normally dispersive medium owing to the negative fifth-order susceptibility inducing a mass of negative frequency chirp. Furthermore, negatively pre-chirped pulses allow for self-compression at lower intensity, avoiding medium damage. We numerically analyze the optimal choice of pre-chirp, input intensity, and medium length.
