A 55, no. 3 (February 1997): 1437-1440.http://hdl.handle.net/10217/67585We 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.born digitalarticleseng©1997 American Physical Society.Copyright and other restrictions may apply.
