X-Ray Lasers 2006

In summary, we have demonstrated intense x-ray lasing from nickel-like plasmas of Mo, Pd, Ag, and Sn by utilizing a short (8 ps) prepulse irradiating the target at a grazing angle of incidence of 22.5°, i.e., collinear with the 3 J, 8 ps main pulse. Saturated lasing has not been proved yet, but comparison with signal levels achieved in previous work suggests that saturation has well been reached i...
