Acousto-optic frequency shifter 1030~1064 nm
The acousto-optic frequency shifter (AOFS) can change the frequency of the beam under the action of the RF driver. Due to the Doppler frequency shift, the frequency shift (wavelength change) of the first-order diffracted light is equal to the frequency of the radio frequency signal (corresponding to the wavelength). If the incident direction of the sound wave and the light wave are the same, the laser frequency shift is a positive value, and if the incident direction is opposite, the laser frequency shift is a negative value.
In the application based on the interference principle, the product requires a high extinction ratio between the first-order diffracted light and the zero-order diffracted light. The acousto-optic frequency shifter produced by Forking Technology can pass the high-quality product smoothness and avoid optical scattering. To meet this requirement.
We provide free-space acousto-optic frequency shifters and fiber-coupled acousto-optic frequency shifters. The center frequency and frequency shift amount of the product can be customized according to customer requirements.
