When a sufficiently intense light pulse propagates through a material, it distorts the atomic configuration, which in turn causes the refractive index to acquire a time dependence. The time-varying index alters the phase of the optical wave as it propagates, leading in general to a broadening of the pulse spectrum. This process has been called self-phase-modulation (SPM) and has been observed by many researchers.1
