Title: Measurement of ultrafast dynamics in the interaction of intense laser pulses with gases, clusters, and plasma waveguides

Abstract

Femtosecond time-resolved dynamics in the interaction of high intensity, ultrashort laser pulses with various targets--gases, nanometer-size clusters, and plasma waveguides--was studied using a new ultrafast optical diagnostic: Single-shot supercontinuum spectral interferometry (SSSI). The diagnostic measures ultrarapid transients induced by an intense laser pulse in the complex refractive index of the evolving target medium, providing a direct view of how the laser-produced disturbances, such as plasma densities, evolve in time and space. Using the SSSI diagnostic (i) the laser-induced double step ionization of helium (ii) time-resolved explosion dynamics of intense-laser-heated clusters, and (iii) the coupling and guiding of intense laser pulses injected into a plasma waveguide were examined.
