Abstract

A self-healing target has been demonstrated for synchronous photo-pumping of extreme- ultraviolet lasers. The threaded, mercury-wetted copper rod, rotating in a pool of mercury, offers similar photoionization efficiency as gold targets, but without target-surface degradation. A gain coefficient of 1.4 cm^-1 was obtained with mercury for the 1089 angstrom Xe²⁺ laser at a pump-laser intensity of 140 GW(DOT)cm^-2, comparing favorably with results from gold targets.
