Time-resolved refractive index and absorption mapping of light-plasma filaments in water

Opt Lett. 2008 Jan 1;33(1):86-8. doi: 10.1364/ol.33.000086.

Abstract

By means of a quantitative shadowgraphic method, we performed a space-time characterization of the refractive index variation and transient absorption induced by a light-plasma filament generated by a 120 fs laser pulse in water. The formation and evolution of the plasma channel in the proximity of the nonlinear focus were observed with a 23 fs time resolution.
