Abstract
The first use of an external cavity diode-laser light source in combin ation with a photoacoustic detector For high-sensitivity gas detection is described. This combined system is applicable for detecting gases with absorption coefficients as low as 5 x 10(-8) cm(-1) by operating the photoacoustic cell in an intracavity mode. Measurements were made on the 1.13 mu m absorption lines of water vapour. For quantitative me asurements, it was found to be necessary to introduce a reference cell into the system.
