  Electron heat conduction is one of the ways that energy transports in laser
heating of fusible target material. The aim of Inertial Confinement Fusion
(ICF) is to show that the thermal conductivity is strongly dependent on
temperature and the equation of electron heat conduction is a nonlinear
equation. In this article, we solve the one-dimensional (1-D) nonlinear
electron heat conduction equation with a self-similar method (SSM). This
solution has been used to investigate the propagation of 1-D thermal wave from
a deuterium-tritium (DT) plane source which occurs when a giant laser pulse
impinges onto a DT solid target. It corresponds to the physical problem of
rapid heating of a boundary layer of material in which the energy of laser
pulse is released in a finite initial thickness.
