Brighter XUV sources are quickly improving. X-ray lasers offer several orders of magnitude higher peak brilliance than third generation synchrotron or other incoherent sources at a narrow emission bandwidth. We present here the set-up of the transient collisionally excited X-ray laser which delivered first pulses at 22 nm wavelength, aswell as the multi Terawatt infrared laser for pumping the X-ray laser. Using the experimental results we can identify corrections to be made in a simple-man’s model of the X-ray laser plasma. Taking into account the rapid development of high power/high energy laser systems our experimental results and analysis might provide usefull input for the development towards high repetition rate X-ray laser systems.
