title: Acoustically resonant pulsed photoacoustic technique for liquids.
abstract: The use of resonant piezoceramic transducers in the pulsed photoacoustic technique and the effect of the focusing of the probing beam have been investigated experimentally. The improved sensitivity for resonant detection and for more tightly focused probing beams has been verified. The constraints imposed when working with tightly focused beams are noted.
