Acousto-optical Frequency Shifters (AOFS)
Transmission through an acousto-optic (AO) device causes the input light to experience a frequency shift equal to the RF drive frequency. Our acousto-optic frequency shifters (AOFS) are optimized for the needs of applications like interferometry, with the ability to achieve high extinction ratio between modes.
We offer standard products with frequency shifts of over 300 MHz and integrated low-power AOFS modules in which the RF driver has been built into the housing. Our team can also customize frequency shifters for specific application, including frequency shifts up to 600 MHz.
Applications
Interferometry, laser cooling, laser Doppler velocimetry, laser Doppler vibrometry (LDV), optical heterodyne detection
