Abstract

The generation of long and homogeneous plasmas by multiphoton ionization of low-pressure gases-H₂, D₂, and N₂ at pressures of a few Torr-rwith a high-power laser at λ=0.53 53 μm. and intensities of the order of 10¹⁵ W/cm² has been studied. The temperature and density of the plasma are measured by Thomson thermal scattering. After the initial full ionization the hydrodynamic density evolution with time is observed. The comparison with a simple model shows that this evolution is mainly due to the ponderomotive force of the laser beam itself. Typical density variations range from 1% to 5% per 100 psec.
