Abstract

Reproducible optoacoustic detection of absorption using a high power pulsed laser is shown to be very sensitive to laser beam geometry and direction through the cell. However, for constant beam conditions the complex substructure and profile of the acoustic signal was found to be invariant with the amount of absorption and the incident laser intensity.
