Homodyne surface second-harmonic generation.
We demonstrate the application of the homodyne mixing technique to surface second-harmonic generation. The technique is shown to have advantages for improving the signal-to-noise ratio for background and detector-noiselimited experiments, for providing real-time measurement of the phase and magnitude of the surface susceptibility, and for simultaneously supplying a normalization signal to cancel effects that are due to laser drift.
