We use the extended nonlinear Schrödinger equation for electromagnetic wave propagation coupled with the plasma equation to unravel the mechanism of the process of white-light generation and describe the temporal, spectral and spatial profiles along the propagation direction for our new development which is a novel arrangement for supercontinuum generation at the 100 μJ level. The result compares well with experimental data. It shows that with a proper spacing between each plate, we can control self-focusing in white-light generation at the GW input power level without invoking beam collapse or distortion, multiple filamentation and damage to the medium.
