Recent experimental results on ion beams produced in high-intensity laser–solid interactions indicate the presence of very intense electric fields in the target. This suggests the possibility of efficiently heating a solid material by means of the

The generation of intense and ultrafast x-ray pulses is a challenge in the study of unexplored physics of high density and high temperature plasmas [1]. Such plasmas are produced when an intense ultra-short laser pulse (100 fs, 1016-17 W/cm2) is focu

High Field Interactions and Short Wavelength Generation.
The propagation of an intense and ultrashort laser pulse in a high pressure gas may be strongly modified because of the fast ionization induced by the intense optical field (1). The fast evolution of the ionization rate of the gas during the laser pu

With high intensity femtosecond lasers it is possible to create plasmas with near solid densities. Such plasmas can bring valuable informations on the dynamics of dense hot solids. They also appear very promising as sources of sub-picosecond X-Ray pu

Short-Wavelength Coherent Radiation: Generation and Application.
Using femtosecond time-resolved Schlieren imaging, we observe a light-induced reversible plasma-like change of the refractive index of a gas during optical irradiation by 80 fs pulses.

In laser-plasma interaction, the electronic temperature can be deduced from the intensity ratio of X-ray lines emitted by highly ionized atoms. Reabsorption of these lines can modify these ratios. We calculate here the intensities of helium-like and

Band-shaped aluminium implants on plane carbon targets were irradiated at 0.1-2*1015 W cm-2 by 600 ps laser pulses of 0.527 mu m wavelength. The resulting blow-off plasmas were diagnosed by X-ray spectroscopy using entrance slits of various dimension

In this paper we present in the first part the new experimental techniques used for the spectroscopic studies of the plasma obtained by laser irradiation of planar target at the GRECO ILM laser facilities. In a second part, we resume the methods used

We present the first space-resolved experimental determination of electronic density and temperature profiles in the transport region for plane target irradiation with 400--600-ps pulses at 0.53- and 0.26-..mu..m wavelengths, and (1--3) x 10/sup 14/-
