Multiple Modulation for Optical Pump-Probe Spectroscopy.

Abstract

A system built largely from readily available amateur radio gear which uses radio frequency and audio modulation of pump and probe light beams allows the detection of very weak signals (rms noise approx. 3 times 10 to the -11th power W for a 10-second time constant) even in the presence of a much larger (0.036 W) background of pump and probe light.
