Fixed and Variable - Frequency Shifters
Fixed and Variable - Frequency Shifters

A frequency shifter uses the shift inherent in the acousto-optic interaction to up- or down-shift a laser’s frequency. Two kinds of shifters are possible:  fixed frequenc shifters and variable frequency shifters. The frequency shift is directly equal to the RF frequency applied onto the transducer (we must not forget that the output angle is also linked to the frequency : see deflectors).

Various techniques can be used to shift the laser beam, such as multiple travels inside the shifter to double or triple the frequency shift, or a combination of two frequency shifters to achieve low amount of shift (DC to KHz). These devices can be used, for example, in optical heterodyning and interferometric applications, or in laser Doppler velocimetry for particle velocity analysis in sprays.
