Coherent Brillouin spectroscopy in a strongly scattering liquid by picosecond ultrasonics

Not Accessible

Your library or personal account may give you access

Abstract

In a modification of a picosecond ultrasonic technique, a short acoustic pulse is launched into a liquid sample by a laser pulse absorbed in a semitransparent transducer film and is detected via coherent Brillouin scattering of a time-delayed probe pulse. With both excitation and probing performed from the transducer side, the arrangement is suitable for in vivo study of biological tissues. The signal is collected from a micrometer-thick layer next to the transducer and is not affected by the diffuse scattering of probe light deeper in the sample. The setup, utilizing a 33nm thick single crystal SrRuO3 transducer film, is tested on a full fat milk sample, with 11GHz acoustic frequency recorded.
