Abstract
Highly nonlinear wave propagation scenarios hold the potential to serve for energy concentration or pulse duration reduction of the input wave form, provided that a small range of input parameters is maintained. Exploitation of this mechanism for pulse compression is ultimately limited by parameter fluctuations of the input wave. With high compression ratios, it becomes increasingly difficult to maintain control of the waveforms. Here, we suggest an alternative approach to the control of waveforms in a highly nonlinear system. Cascading pulse self-compression cycles at reduced nonlinearity limit the increase of input parameter sensitivity while still enabling an enhanced compression effect. This cascaded method is illustrated by experiments and by numerical simulations of the nonlinear Schrödinger equation, simulating the propagation of short optical pulses in a self-generated plasma.
