Controlling Charged-Particle Fluxes in the Erosive Laser Plasma of a Graphite Target in Vacuum

  • TRANSFER PROCESSES IN LOW-TEMPERATURE PLASMA

Journal of Engineering Physics and Thermophysics Aims and scope

Parameters of the erosive laser plasma of a graphite target on exposure to Nd3+:YAG-laser pulses with a wavelength λ = 1064 nm and a pulse duration τ ~ 20 ns have been investigated. Two zones of glow have been found. One zone is quiescent and is located at the target surface at the site of exposure to laser radiation. The other glow zone moves opposite to a laser beam with a velocity of ~10 km/s. A method to control charged-particle fluxes in the erosive laser torch has been proposed.
