During the first plasma phase defined by the duration of laser-target interaction, the time derivative of the target current matches the time-resolved laser intensity. The second phase of the laser-produced plasma starts after termination of the laser-matter interaction. For the entire duration of this active phase, the plasma surviving on the target surface emits transient electromagnetic radiation (EMP), X-ray radiation, and slow ions. This surface plasma causes the target charging balanced by a return target current on a time scale of 100 ns. Then the target holder acts as a probe, the signal of which can indicate a residual plasma persisting inside the target chamber on a time scale of microseconds.
