Abstract

A charge-exchange pumping of laser-produced ions on a compact gas cloud is experimentally investigated. An interaction at density of neutrals approximately equals 10¹⁶ cm^-3 has been achieved for the first time. A record efficiency of charge-transfer pumping 10% has been measured which is close to maximum 25% predicted by developed analytical model. The results obtained appeared to be in good agrement with 3-D numerical simulation and are promising for future laser gain experiments.
