给出了两种计算短脉冲入射到线性介质上的反射波的方法。作为例子，计算了输入sech脉冲调制谐振载波和输入增量函数的情况。当原子密度大于约1018个原子cm-3时，就会反射出相当数量的Sech脉冲能量。有人认为，任何忽略反射的非线性理论都可能在这些密度下崩溃。
Two methods of calculating the reflected wave generated by a short optical pulse falling on a linear dielectric medium are given. As examples the cases of an input sech pulse modulating a resonant carrier wave and an input delta function are calculated. At atomic densities greater than about 1018 atoms cm-3 an appreciable amount of the energy of the sech pulse is reflected. It is suggested that any nonlinear theory which ignores reflection may break down at these densities.
