Paper Abstract

The white-light continuum generation (WLCG) has been widely used as a probe beam for the ultrafast time-resolved difference absorbance spectrum or the seeding beam in an optical parametric amplifier (OPA). Therefore reducing the chirp effect in WLCG would be important. We report the study on WLCG in different medium by focusing 800nm laser pulse with a pulse duration of 150fs into 2mm thick CaF2, 2.4 and 0.5mm sapphire plates, try to find any medium as well as the optical pathlength effect on the chirp of the WLCG. The chirped dispersion of WLCG was determined by optical Kerr effect. The results show that the temporal span of the WLCG is almost independent on the optical pathlength of the medium in the observed spectral region, while it has an obvious dependence on the different media used.
