The temporal and spatial electron density distribution and the temporal variation of electron temperature have been determined in gaseous deuterium plasmas produced by a laser. In addition to these measurements, made during laser irradiation of the plasma, the plasma growth rate, laser-plasma absorption and reflection interaction, and pressure dependence of laser intensity breakdown threshold have been determined. A time-variable reflectivity ruby laser with a pulse duration of 4 nanoseconds was employed in these experiments at gas pressures from 100 to 600 torr. The electron density and temperature measurements represent a major addition to the data available on laser-produced plasmas. Author
