Temporal analysis of processes induced by a resonant laser in a dense In vapor

This work illustrates the temporal analysis we have done on the fluorescence signals originating from levels with pecularly different characteristics populated either via Energy Pooling Collision (EPC) or via Energy Pooling Ionization (EPI). The fluorescence from the first excited level (S ia) gives informations about the limited radiation trapping due the fine structure of the ground state l/2 3/2 the ones from the 1 1P and 5D levels allow to discriminate between the different population mechanism, EPC and EPI respectively. The cross sections for the two different processes may also be obtained.
