| Abstract: | A time and space resolved diagnostic technique was used to study the properties of plasma produced by a pulsed laser on an Al target irradiated at different ambient pressures. The velocities of projected particles were measured. The projected ranges for 1-10keV AI2+ ions ejecting into ambient gas at different pressures were calculated in theory. The calculated results can explain the observed experimental phenomena successfully. |
