Observation of gain in a possible extreme ultraviolet lasing system
Abstract
Measurements of gain by stimulated emission of the Balmer α line of the hydrogenic ion, C VI, at 182 Aring; are reported. The population inversion is generated by recombination in the expansion of a carbon fibre heated by a line focussed laser pulse. The gain is identified by observations using two calibrated spectrographs from the ratio of intensities, and by spectral line modification. Gain/length products of value up to 5 are deduced.
