High-gain x-ray lasing at 11.1 nm in sodiumlike copper driven by a 20-J, 2-ps Nd:glass laser
Optics Letters 21:14 (1996) 1035-1037
Abstract:
Evidence of high gain pumped by recombination has been observed in the 5g-4f transition at 11.1 nm in sodiumlike copper ions with use of a 20-J 2-ps Nd:glass laser system. The time- and space-integrated gain coefficient was 8.8 ± 1.4 cm-1, indicating a single-transit amplification of ∼60 times. This experiment has shown that 2 ps is the optimum pulse duration to drive the sodiumlike copper recombination x-ray lasing at 11.1 nm. © 1996 Optical Society of America.Characteristics of rapidly recombining plasmas suitable for high-gain X-ray laser action

Abstract:
Recombining plasmas produced by picosecond laser pulses are characterized by measuring ratio of intensities of resonance lines of H- and He-like ions in the plasmas. It is found that the rapidly recombining plasmas produced by picosecond laser pulses are suitable for high-gain operation.Coherence and bandwidth measurements of harmonics generated from solid surfaces irradiated by intense picosecond laser pulses
