We observed, for the first time to our knowledge, soft-x-ray 3p–3s lasing in neonlike zinc and arsenic in the wavelength interval 212–267 A, with gain coefficients ranging from 2.0 to 5.4 cm−1. Also, spectral lines were observed in neonlike gallium at the wavelengths predicted for lasing. A single-beam, driving laser (λ = 1.05 μm) at pulse energies of up to 500 J, with rise times of ~0.6 ns and pulse durations of 1–2 ns, was used with slab targets. Time-integrated diagnostics were used. We…
