Acousto-Optic Frequency Shifters

Specific frequency shifting of laser beams in the range from approximately 10 to 300MHz.

Supplier: Isomet

Technology type: Acousto-Optics

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.

Wavelength range: 325nm up to 10,600nm
Optical materials: PbMoO4, TeO2, Ge, fused silica
Centre frequencies: ca. 100 - 350MHz
Tuning bandwidth: 2.5 - 100MHz

Active apertures: ca. Ø 0.2mm up to 6mm
Special designs according to customer requirements available
Suitable RF drivers, synthesisers, and amplifiers
