Abstract: | We present results of experimental and computational investigation of laser plasma emission in the soft x-ray spectrum. Plasma has been produced by irradiating a gold target with subnanosecond pulses at the first and second harmonics of an iodine laser. It has been shown that approximately half of the absorbed laser energy is converted into soft plasma x-rays.Presented at bilateral international seminar of High Temperature Laser Plasma and High Gain Iodine Lasers held on 4 July 1991 in the Inst. of Physics, Czechosl. Acad. Sci., in Prague (organized by Division of Optics of the Inst. of Physics, Czechosl. Acad. Sci., and Physical Section — Plasma Division of the Union of Czech Mathematicians and Physicists). |
