A Two-Channel High-Frequency Acousto-Optic Modulator

Аннотация

The design of a two-channel acousto-optic modulator transforming the frequency shift of optical radiation into the high-frequency amplitude modulation is presented. A large- aperture modulator with two orthogonally polarized output optical beams has been produced from a TeO₂ single crystal for modulating radiation with a wavelength 0.63 µm and tested. The amplitudes of the beams are modulated at a frequency of approximately 100 MHz, and the beam modulations are in antiphase.
