M. A. Musayev and I. I. Abbasov The laser generation of sound waves in strongly absorbing liquids is discussed. We demonstrate the experimental method to determine simultaneously both velocity of sound and light-absorption coefficient in liquids. With this method, measurements of these values for different oils are carried out, and the temperature coefficients of velocity of sound and gummosity are determined. Key words: optoacoustical signal, absorption coefficient, acoustic wave, sound speed, gummosity. https://doi.org/10.15407/nnn.15.04.0611 REFERENCES 1. M. W. Sigrist, J. Appl.
