Abstract
Environmental noise induces frequency instabilities in lasers. By analyzing these instabilities, we can determine the characteristics of the noise and thus identify the source, using the laser, in effect, as a supersensitive "microphone." The techniques described in this paper can be used for supersensitive detection and identification of extremely low-level noise sources.
