“…Low-density gases are, in general, rather inefficient at absorbing laser light and the plasmas that result are usually of modest temperature. At sufficiently high intensities, the growth of plasma instabilities can also heat the gas sufficiently to produce short-wavelength emission [13]. Gases containing atomic clusters of a few hundred to a few thousand atoms, however, exhibit very efficient absorption of the laser light even if the average density of the gas is low [8].…”

We have studied the characteristics of x-ray emission in the 12-16Å range from plasmas produced by the irradiation of a target of Xe clusters with picosecond laser pulses at intensities near 10 17 W cm −2 . These plasmas exhibit strong emission from Ni-like through to Mn-like Xe. We find that the strength and character of the x-ray spectra are very similar when either 1053 or 526 nm laser pulses are used to heat the clusters.

“…This peculiarity is not only responsible for completely new relaxation and recombination processes [44,47], but is also the cause of the development of plasma instabilities [46,49,51], which in turn influence and modify the photo-electron kinetics. Investigations on these issues, both experimental and theoretical, are already available in the literature and are steadily growing (see, for instance, [52][53][54][55][56]). A detailed analysis and review of these and similar investigations are outside the scope of our short review.…”

A short review of the properties of electron distribution functions in a fully ionized plasma in the presence of high-frequency laser radiation is given. Weak and strong field situations are considered. In a weak field, when the amplitude of the electron quiver velocity in the field is smaller than the electron thermal velocity, the distributions of both the thermal and the under thermal electrons are considered. The conditions are shown when it is necessary to take into account the deviation of the electron distribution function from a Maxwellian. In a strong field the kinetics of the electron is strongly determined by the field intensity and the distribution function in the coordinate system oscillating with the radiation frequency is anisotropic under broad physical conditions, and may be approximated by a bi-Maxwellian distribution with two different transverse and longitudinal temperatures. Among the most peculiar features of the laser modified electron distribution functions, it is worth quoting the pathway of the anisotropy evolution. Depending on the laser field parameters, the distribution function in the initial stages of the laser-plasma interaction is either elongated or squeezed parallel to the field polarization. In the later stages it evolves towards isotropization, which is always approached from the elongated shape. Thus, an initially squeezed distribution function first evolves towards an elongated shape and subsequently towards isotropization. The physical origin and the consequences of the reported features are discussed. In addition, a number of physical processes for which the theory demands the use of the described non-equilibrium distribution functions are briefly addressed.
