Paper Abstract

We describe recent experiments at the Lawrence Livermore National Laboratory (LLNL) to produce a table-top x-ray laser. Using a combination of long 800 ps and short approximately 1 ps high power laser pulses with approximately 6 J in each beam, a transient collisionally excited Ne-like ion x-ray laser scheme has been investigated. We present results of high x-ray laser gain for the Ne-like Ti 3p - 3s J equals 0 - 1 transition at 326 angstrom and have achieved gL product of 15 for target lengths up to 1 cm. We have extended the transient collisional scheme to shorter wavelengths using the Ni-like analog, specifically the 4d - 4p J equals 0 - 1 of Ni-like Pd at 147 angstrom.
