“…There are many possible applications which can be pursued with table-top x-ray lasers but have previously required larger laser facilities to pump the inversion. These include x-ray microscopy (29), interferometry of plasmas (30), radiography of plasmas (31), and interferometry of materials (32). X-ray laser applications are enhanced by the high repetition shot rate and inherent short pulse duration available with table-top transient gain x-ray laser systems.…”

Abstract. We present recent results of x-ray laser amplification of spontaneous emission in Ne-like and Ni-like transient collisional excitation schemes. The plasma formation, ionization and collisional excitation can be optimized using two laser pulses of 1 ns and 1 ps duration at table-top energies of 5 J in each beam. High gain of 35 cm -1 has been measured on the 147 Å 4d→4p J=0→1 transition of Ni-like Pd and is a direct consequence of the nonstationary population inversion produced by the high intensity picosecond pulse. We report the dependence of the x-ray laser line intensity on the laser plasma conditions and compare the experimental measurements with hydrodynamic and atomic kinetics simulations for Ne-like and Ni-like lasing.

International audienceOne interest of extreme ultraviolet wavelengths is their potentially high optical resolution. Such optics require high precision, low roughness surfaces onto which will be deposed adequate multilayers giving near-normal incidence reflection. For a spatially resolved interferometer, we have manufactured and tested with a reasonable degree of confidence an 8×8 mm off-axis ellipsoidal mirror, below the diffraction limit for a 14 nm wavelength. The ion beammilling technique employed for the fabrication allows to preserve the low roughness of the initial spherical substrate, and although we only achieved a 0.4 nm root-mean-square roughness, better could easily be done. At these precisions, testing is as important and as difficult as the figuring itself. The resulting mirror combines high theoretical resolution (1 μm) over a large object field (∼1 mm in diameter)
