Abstract

It is demonstrated that the photoacoustic effect in an external cell is a sensitive resonant detector of intracavity absorption. The detection limits for I2 and Br2 are 3 ng/cm3 and 48 ng/cm3, respectively. For the case of I2 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.
