Product description:

The acousto-optic frequency shifter(AOFS) with RF driver is used to modify the frequency of the optical beam. Due to the Doppler shift, the frequency shift of 1st order diffracted light (variation quantity of wavelength) equals to the frequency of RF signal (wavelength). If the incident direction of acoustic wave and optic wave are the same, the shifted laser frequency value will be  positive, on the other hand, if the incident direction of acoustic wave and optic wave are opposite, the shifted laser frequency value will be negative.

Applications such as interference-based optical techniques require a high extinction ratio between the diffracted and undiffracted beam.

CASTECH provides customized specs including center frequency and the shifted frequency value.

 

Applications:

● Interferometry

● Laser cooling

● Laser Doppler velocimetry

● Optical heterodyne detection
