Using the technique of laser probing, the time dependences of the transparency factor, integral glow, and of the scattered component of probing radiation for erosional laser jets of metals exposed to intense submicrosecond laser pulses have been determined. Based on the results of laser probing, a conclusion on the condensation nature of the process of formation of a liquid-droplet phase of the target-material under the given conditions of laser action has been drawn.
