A mixer based electro-optic sampling system for submillivolt signal detection

Abstract
We report on a new technique which allows electro‐optic sampling to be performed in a frequency range which is above the 1/f noise regime of the pump‐probe laser, while at the same time utilizing the high‐sensitivity, low‐noise properties of an audio‐frequency lock‐in amplifier. This new approach to electro‐optic signal extraction has resulted in an unprecedented improvement of two orders of magnitude in signal‐to‐noise capability. The new technique is compared to previous, conventional approaches.
