TL;DR: Photometric measurements of the 330-nm return flux confirm previous theoretical studies that the PLGS process should allow us at a later stage to correct for the tilt at wavelengths as short as approximately 1 microm at good astronomical sites, and show that, at saturation of two-photon coherent absorption in the mesosphere, the backscattered flux increases by a factor of approximately 2 when the pulse repetition rate decreases by a factors of 3 at constant average power.

TL;DR: In this paper, the authors presented and discussed time resolved spectra (KeV range) of solid density plasmas produced by the interaction of clean high intensity laser pulses (400 fs, 0.53 im light) with solid and foil targets at intensities between 1018 W/ cm2 and 1020 W/cm2.

TL;DR: In this article, an x-ray emission near the He-α resonance line from high-intensity (>1019 W/cm2) sub-picosecond laser-plasma interaction is presented.

TL;DR: In this article, the spectral sensitivity of a multi-image framing camera based on gated MicroChannel Plates (MCPs) was measured using synchrotron radiation on the storage ring SUPERACO in Orsay (France).

TL;DR: In this paper, the brightness theorem was used to couple the photoelectron emission from the virtual cathode, through the anode aperture, to the recording screen, and it was shown that higher throughputs are obtained when using a slot, rather than a mesh, for the accelerating electrode.
