Abstract
Langmuir probes were used to monitor the asymptotic expansion of the plasma produced by the laser ablation of a silver target in a vacuum. The measured angular and temporal distributions of the ion flux and electron temperature were found to be in good agreement with the self-similar isentropic and adiabatic solution of the gas dynamics equations describing the expansion.
The value of the adiabatic index gamma was about 1.25, consistent with the ablation plume being a low temperature plasma.
