It is demonstrated that the photoacoustic effect in an external cell is a sensitive resonant detector of intracavity absorption. The detection limits for I/sub 2/ and Br/sub 2/ are 3 ng/cm/sup 3/ and 48 ng/cm/sup 3/, respectively. For the case of I/sub 2/ the detection limit using the photoacoustic detector is essentially the same as the detection limit using a fluorescence detector. The sensitive response of photoacoustic detection to IR absorption makes this technique particularly attractive as a potential resonance detector for intracavity absorption with IR lasers.
