Abstract

Analysis shows that the isolation inherent in acoustooptic modulators is impaired if the acoustic wave is partially retroreflected. This effect generates additional spectral components in both the deflected and the retroreflected light beam. The theoretical findings were confirmed by experiments at 10.6 μm, where an optical isolation of 40 dB was measured for a device with 23% deflection efficiency.
