Abstract : A plasma was produced by the interaction of 300 MW, 25 nsec, Nd laser pulse with an aluminum target. The resulting plasma expanded into an ambient background of 0.000025 torr and was analyzed using floating double probes, magnetic probes and a quartz pressure probe. An early disturbance was noted before arrival of the main plasma. Further experiments separate this early signal into photoelectric response and two fast plasma pulses traveling with constant speeds of 1.1 X 10 to the 8th power cm/sec and 5.9 X 10 to the 7th power cm/sec.
