Abstract
When a solid target is irradiated by an intense pulse of laser light, an inhomogeneous plasma is created (Fig. 1). A low-density ideal plasma (ne < 1021 cm−3) expands toward the laser; this hot blowoff region refracts and absorbs the laser beam. The absorbed energy is conducted into a dense plasma region (ne = 1021 to 1023 cm−3) where the heat flow is converted into hydrodynamic motion of the exploding plasma. The large reaction pressure shocks the target surface, compressing it above the initial solid density into a state which may be called high-density matter (ne > 1023 cm−3).

A review of the experimental situation and some proposed explanations is given by W. Kruer, Comments on Plasma Physics 5, 69 (1979).
A Fokker-Planck calculation of transport by non-Maxwellian free electrons has recently been performed by J. Albritton at LLNL. The calculations indicate that distortion of the tail of the Maxwellian tends to inhibit electron thermal conduction.

The result given here is based, in part, on an unpublished study of nonequilibrium thermodynamics by F. Keffer and R. More.
The conclusion reached here contradicts an analysis given by C. Kittel, Elemental Statistical Physics, p. 165–168, J. Wiley, New York, 1958. A careful comparison will show that the textbook treatment omits the spontaneous emission factor included in our Eq. (6–2). This omission is effectively equivalent to selecting a very high radiation temperature (so that Ny >> 1), but in this case one cannot Δachieve AT << Te. Thus it is not surprising that the (incorrect) rate equations given by Kittel are incompatible with the principle of minimum entropy production. Footnote 59 applies also to these remarks.
