Acousto-Optic Frequency Shift (AOFS) | SIMTRUM Photonics Store

AO-Frequency Shifters

An acousto-optic device that converts the frequency of input light to the frequency of an RF drive

After the laser beam passes through all the acousto-optic devices, the diffraction output beam will generate a frequency shift. Acousto-optic frequency shifters (AOFS) are compact devices specially designed for frequency shifts. Depending on the selected angle of incidence, the AOFS will shift the frequency up or down by the frequency of the applied RF signal, and two or more devices can be cascaded to achieve a sum or difference frequency combination. SIMTRUM offers AOFS products that adopt specially designed acoustic absorber angles to minimize sound reflection and improve the efficiency of AOFS.

In addition to the conventional TEO2-based products, SIMTRUM’s AOFS also offers a variety of products, including UVFS and Ge single crystals, which can be used individually or in a cascade to achieve a 15-250 MHz frequency shift as required.
