Abstract

The authors report a novel technique for interrogating a network of intracavity absorption sensors. The technique is based on a mode-locking principle where different sensors are addressed by their associated mode-locking frequencies. Experiments with a two-sensor network demonstrated negligible crosstalk between sensors and a sensitivity of 128 times better than that of a single-pass direct absorption sensor.
