Abstract :
We present an accurate calculation of the intensity of the second harmonic radiation generated by the reflection of the incident radiation from a metal surface. This radiation is due to two currents. The first current results from the rapid variation of the normal component of the oscillating electric field in the vicinity of the surface and depends on both conduction and bound electrons. The second one results from the action of the Lorentz force on conduction electrons. We show that if the adiabatic and the Thomas-Fermi assumptions are considered, then an accurate calculation of these currents is possible and leads to a simple relation of the intensity of the second harmonic radiation
