热锋的形成和传播所产生的强烈的飞秒激光脉冲的数值模拟治疗自洽激光吸收，热传导和流体力学检查。结果表明，初始热锋是由作为倏逝波的激光吸收决定的。随着固体温度的升高，热传导的影响变得重要。结果还表明，这样的热锋可用于探测热，致密等离子体的电导率和热导率。
The formation and propagation of heat fronts produced by an intense femtosecond-laser pulse are examined in numerical simulations which treat self-consistently laser absorption, thermal conduction, and hydrodynamics. The results revealed that the initial heat front is dictated by laser absorption as an evanescent wave. The effect of thermal conduction becomes important as the temperature of the solid increases. The results also suggest that such heat fronts may be used to probe the electrical and thermal conductivities of hot, dense plasmas.
