A new heat flux formula valid in strong inhomogeneous laser-produced plasmas has been derived from the Fokker--Planck equation. The nonlocal treatment of Luciani et al. (Phys. Rev. Lett. 51, 1664 (1983); Phys. Fluids 28, 835 (1985)) is improved by taking into account the electric potential effect. A simple and reliable phenomenological formula is proposed, which is in good agreement with numerical Fokker--Planck computations.
