Summary
A pulsed ruby laser beam with 3 nsec full width at half magnitude is used to obtain space- and time-resolved, two-dimensional interferometric measurements of electron number density in CO/sub 2/-laser produced plasma in hydrogen near the focal spot. The focal plane of the CO/sub 2/ laser is arranged to be at the exit of a free-expansion jet, with the beam incident from the vacuum side. Several nanoseconds after breakdown, a shock wave is formed, propagating transverse to the incident laser beam direction. Behind the transverse propagating shock is an on axis density minimum, which results in laser-beam self trapping. During the initial pulse duration of the CO/sub 2/ laser, the radial boundary of the plasma column increases linearly in time.
