General method of passive optical pulse peak intensity stabilization through controlled self-phase modulation and over-compression

Original language description

A method of peak intensity stabilization of optical pulses is presented which is based on the combination of self-phase modulation (SPM) and an optical compressor. Spectral broadening via SPM can occur for intense laser pulses propagating through a nonlinear medium. For Gaussian pulses, this nonlinear broadening results in a nonlinear spectral phase, which positively chirps the pulse. Because this is a nonlinear process, the amount of spectral broadening depends on the intensity of the laser pulse with increased broadening for higher intensities. Here we propose a technique of peak intensity stabilization by accumulating a modest amount of nonlinear spectral phase on a pulse via SPM and subsequently introducing a negative net group delay dispersion (GDD) with an optical compressor. For the appropriate value of compressor GDD, the energy-dependent chirp is balanced such that the peak intensity of the pulse is stabilized.
