Doppler-limited high resolution laser optogalvanic spectra of six transitions of rhenium lying in the range 560–620 nm have been recorded. Isotope shifts between the two natural isotopes of rhenium,185Re and187Re, have been calculated in all the six transitions. Hyperfine coupling constants for eight levels belonging to the configurations 5

A one dimensional numerical model to simulate the laser matter interaction in the presence of an ambient gas is presented. The model is developed by making appropriate modifications in MEDUSA, a one dimensional Lagrangian computer code, which simulates laser plasma interaction in vacuum. Various parameters of the plasma such as velocity, electron temperature, ion temperature, density, pressure, shock wave intensity of the plasma as it expands into a background gas are simulated. The results are compared with the experimental observations.
