Soft-x-ray amplification in a laser-produced strontium plasma

Abstract

Amplification of soft x rays in Sr tZ=38) plasmas produced by second-harmonic laser irradiation of exploding foil targets is studied. Gains of 4.4 and 4.0 cm ', respectively, have been measured for 0

Soft x-ray emission from laser-produced strontium ions

“…Strontium has been shown to be a candidate for high brightness x-ray laser applications. Soft x-ray amplification at 16.41 and 16.65 nm in a plasma generated by 0.53 micron laser irradiation in Ne-like Strontium ion have been reported [11]. 3d-4p resonant transitions and 3d4s-3d4s4p satellite transitions in some strontium ions have already been reported collectively in a table of atomic data [6].…”

Oscillator strength anomalies in the neon isoelectronic sequence with applications to x-ray laser modelling

“…2p 3/2 4d 5/2 [J = 1]: present work --; Cornille et al (1994) •; Zhang et al (1989) . neon-like strontium spectrum have been identified by Wyart et al (1987), and Keane et al (1990) observed soft x-ray amplification in a laser-produced strontium plasma. The table reveals good agreement between the different theories for the strongest RTP (greater than 10 9 s −1 ), but continued disagreement for the 2p3p[0]-2p3s[1] group as discussed by Ivanov et al (1995).…”

“…IG: present work; Q: Quinet et al (1991); C: Cornille et al (1994). Experimental wavelengths: w: Wyart et al (1987), k: Keane et al (1990) created by a high-contrast, high-intensity, short-pulse laser driver. If the ionization and dielectronic recombination rates are nearly balanced, the duration of the lasing under these conditions is determined by plasma cooling rather than by the rate of disappearance of the Ne-like ionization stage.…”
