Abstract Methods for enhancing the photoacoustic signal for both the gas microphone and the piezoelectric detection techniques are described. Measured values of the enhanced signals are comparable to the values predicted by theory. The ability to increase the photoacoustic signal may be particularly valuable in investigations where low light intensity is desirable to avoid surface damage or where the sample itself gives a very weak signal.
