Recombination Processes of Multi-Charge Ions of a Laser Plasma

The presence of an obstacle on the path of laser plasma expansion in vacuum leads to an increase in the ion charge multiplicity, an expansion of the energy spectrum, and an increase in the total number of ions. The peculiarities of the interaction with a solid-state obstacle are largely associated with the appearance of a shock wave in it, which affects the course of recombination processes. It is shown that it is possible to control the parameters of a recombining laser plasma by changing the expansion dynamics at later stages using solid-state obstacles.
