Investigations on novel XUV-laser schemes.

Short pulse laser generated plasmas interacting with a pulsed gas jet are studied to aid the realization of novel XUV laser schemes based on recombination supported by charge exchange pumping. Interaction of C4+, O3+ and O4+ ions with hydrogen and nitrogen indicates strong charge exchange pumping of C3+(3p-2s, 3d-2p) lines at 31.2 and 38.4 nm, and O2+ (2p 3s-2p2) and O3+ (2s 3d-2s22p) lines at 37.4 and 23.8 nm.
