Charge-transfer pumping of O+5 ions with emission at 51.2 nm

A charge transfer pumping as a possible tool for lasing in XUV is investiga ted in the Institute of Laser Physics, Novosibirsk. A new scheme based on t he laser-produced plasma colliding with the laser-evaporated gas was previo usly proposed and tested. It showed that lasing at 51.2 nm can be achieved on the 4-3 transition of Li-like O+5 ion. Preliminary results on the enhanc ed emission at 50 nm and on the specifics of charge transfer reaction O+6 H-2 --> O+5 + H+ are reported.
