Abstract
Ultra-short pulses of high peak power are useful in many applications such as spectroscopy, laser ablation, remote sensing and medical treatment [1]. The optical pulse compression is an attractive technique to generate ultrashort pulses by compression of short pulses using specially designed nonlinear fiber. Pulse compression is the consequence of interaction between self-phase modulation (SPM) and group velocity dispersion (GVD). An axially varying fiber is an interesting approach to achieve pulse compression through a short length of the fiber [2].
