Adak, Amitava, Blackman, Dave, Chatterjee, Gourab et al. (6 more authors) (2016) Probing ultrafast dynamics in a solid-density plasma created by an intense femtosecond laser. Journal of Physics: Conference Series. 012001. ISSN 1742-6596
Abstract
We report a study on the dynamics of a near-solid density plasma using an ultraviolet (266 nm) femtosecond probe laser pulse, which can penetrate to densities of ∼ 1022 cm-3, nearly an order of magnitude higher than the critical density of the 800 nm, femtosecond pump laser. Time-resolved probe-reflectivity from the plasma shows a rapid decay (picosecond- timescale) while the time-resolved reflected probe spectra show red shifts at early temporal delays and blue shifts at longer delays. This spectral behaviour of the reflected probe can be explained by a laser-driven shock moving inward and a subsequent hydrodynamic free expansion in the outward direction.
