Frequency Shifters (AOFS)

An acousto-optic frequency shifter (AOFS) is a device that modifies the frequency of the optical beam. This is a consequence of the interaction with the acoustic wave; the travelling acoustic wave causing the frequency of the optical beam to be either increased or decreased by an amount equal to the RF carrier frequency. Since the RF frequency is typically of the order of tens or hundreds of Megahertz, and the optical frequency is typically of the order of 1014Hz, the frequency shift is relatively small and would not normally be perceivable, for example as a visible change in color. 
Utilizing a wide range of materials including Crystal Quartz, Fused Silica, Tellurium Dioxide, Lead Molybdate, Chalcogenide Glass, Gallium Phosphate, Silicon and Germanium allows us to offer devices operating in the wavelength range 244nm to 15µm and RF frequencies ranging from 
Typical applications include Interferometry, vibrometry and atom cooling. The models in the table shown below are typical representatives, but many of the standard modulators and deflectors can also be used as frequency shifters.
