We present in this work a kinetic model which describes the evolution of charged particles produced by high-intensity, ultrashort laser pulses in nonresonant multiphoton ionisation (MPI). The numerically predicted waveforms of the ion detector signal are compared to those observed in nonresonant MPI of Xe with 30 psec, 10(13) W/cm2, 1.064 mum laser pulses. The comparison highlights the relevance of space charge effects in typical nonresonant MPI conditions, and shows the effectiveness of our model in accounting for them.

Abstract
We present in this work a kinetic model which describes the evolution of charged particles produced by high-intensity, ultrashort laser pulses in nonresonant multiphoton ionisation (MPI). The numerically predicted waveforms of the ion detector signal are compared to those observed in nonresonant MPI of Xe with 30 psec, 10(13) W/cm2, 1.064 mum laser pulses. The comparison highlights the relevance of space charge effects in typical nonresonant MPI conditions, and shows the effectiveness of our model in accounting for them.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
