We present results of experimental studies on transient gain soft x‐ray lasers with a picosecond‐laser‐irradiated gas puff target. The target in a form of an elongated gas sheet is formed by pulsed injection of gas through a slit nozzle using a high‐pressure electromagnetic valve developed and characterized at the Institute of Optoelectronics. The x‐ray laser experiments were performed at the Lawrence Livermore National Laboratory using the tabletop Compact Multipulse Terawatt (COMET) laser to irradiate argon, krypton or xenon gas puff targets. Soft x‐ray lasing in neon‐like argon on the 3p‐3s transition at 46.9 nm and the 3d‐3p transition at 45.1 nm have been demonstrated, however, no amplification for nickel‐like krypton or xenon was observed. Results of the experiments are presented and discussed.
