Abstract

We investigate the influence of the time-dependent on-axis phase matching on broadband extreme ultraviolet (XUV) supercontinuum generation with an intense laser field. By using the strong-field approximation model and solving Maxwell’s equations we show that time-dependent on-axis phase matching can lead to broadening of the XUV supercontinuum. Moreover, we also demonstrate that the bandwidth of the XUV supercontinuum can be controlled by adjusting the beam waist of the laser field and the position of the gas medium.
