摘要：

The generation of second harmonic by a laser incident obliquely on a thin metal film grown on a glass substrate is studied. The laser imparts a nonlinear current to the electrons of the metal film, which generates the second harmonic in the reflected component. The second harmonic radiation is sensitive to angle of incidence and film thickness. For a particular set of parameters, the second harmonic amplitude is similar to 23% of the incident laser amplitude.
