Time resolved transient absorption probing of a laser plasma

M. Hemici , S. Mottin , M. Bon , J.-Y. Roncin , P. Laporte

The described experimental setup allows the kinetic analysis of a pulsed-laser generated gas-plasma by transient visible absorption spectroscopy at a time resolution of 10 ns and a spectral resolution of 0.3 cm-1. Absorption from the first-4s level manifold towards the 5p level manifold of the argon atom is reported in the spectral range around 420 nm. An example of time dependence is given for the 4s[3/2]2 level population.
