Occurrence of erosion processes in the near-surface region of metals exposed to intense nanosecond laser pulses

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Using the method of laser probing, the time dependences of the transparency factor and integral luminescence of erosional jets of metals appearing upon their exposure to intense nanosecond laser pulses, as well as of the probing radiation component scattered by the jet, have been determined. Based on the results of laser probing, a conclusion was drawn on the condensation nature of the process of liquid-droplet phase formation near the surface of investigated metals in the considered conditions of laser effect on them.
