Isomet’s acousto-optic frequency shifters (AOFS) are specially designed for use with laser beams. After the AOFS the diffracted laser beam is shifted by the amount of the respective centre frequency of the AOFS. Depending on the law of Bragg angle, the laser frequency is either decreased or increased (down-shifted or up-shifted).
For frequency shifts of a laser beam smaller or larger than the centre frequency of the AOFS, two or more units can be cascaded to achieve a difference or summation of the respective shifts. Corresponding RF drivers are also available.
