摘要：

We report the observation of discharge-pumped extreme ultraviolet lasing in collisionally excited ions of a material ablated from a solid target. Excitation of sulfur plasmas by a capillary discharge resulted in amplification of the J = 0-1 line of Ne-like sulfur at 60.8 nm, with a gain coefficient of 0.45 cm(-1) and a gain-length product of 7.5. Overheating of the electron temperature and transient population effects are computed to make a significant contribution to the measured gain.
