Abstract
The effectiveness of pulsed laser photoacoustics in the spectral analysis of water at high pressures is studied. The pulsed photoacoustic response from distilled water at 20 °C for a range of pressures from 1-350 bars is considered. The combination of pressure dependences of each physical parameter is expressed in terms of the pulsed photoacoustic signal, detected by an acoustic transducer. The results indicate that the accepted principles and theories describing pulsed photoacoustic generation hold true for liquids under high pressures.
