摘要
In this paper, we give the distribution of temperature field and pulse photoacoustic pressure generated by pulsed laser in liquid. The effect of pulse duration and laser beam dimension on the pressure signal is discussed. The experimental results obtained by the Gauss laser beam deflection technique agree with the theory qualitatively. This technique provides a novel optical method for the contactless and rapid measurement of thermodynamic parameters.
