We report on a new technique which allows electrohyphen;optic sampling to be performed in a frequency range which is above the 1/fnoise regime of the pumphyphen;probe laser, while at the same time utilizing the highhyphen;sensitivity, lowhyphen;noise properties of an audiohyphen;frequency lockhyphen;in amplifier. This new approach to electrohyphen;optic signal extraction has resulted in an unprecedented improvement of two orders of magnitude in signalhyphen;tohyphen;noise capability. The new technique is compared to previous, conventional approaches.
