Paper Abstract

We have proposed a new theoretical method for measuring the Brillouin gain of liquids by analyzing the pulse compression ratio that the pump pulse duration to the output Stokes pulse duration. The theoretical model of the pulse compression ratio is presented based on coupled wave equations. The Brillouin gain coefficient can be determined by measuring the pulse compression ratio, the pump intensity and the characteristic length. The application on the measurement of gain coefficient of SBS in some Newtonian liquids will be the subject of further studies.
