The process of thermo-optical excitation of sound by opposing light waves is studied in the magnetically active medium. The influence of natural and induced optical activity on the resulting photoacoustic (PA) response is analyzed. A method of controlling the amplitude of PA signal is proposed. The method is based on the possibility to affect the interference energy dissipation by an external magnetic field.
