| Product Introduction

Acousto-optic Frequency Shifter (Acousto-optic frequency shifter,AOFS) are compact devices designed specifically for frequency shifting. After the Laser Source beam passes through the Acousto-optic Frequency Shifter, the Diffraction output beam is shifted in frequency. Depending on the Incident Angle selected, the AOFS will up-shift or down-shift the frequency by the frequency of the applied RF signal, and may cascade two or more devices to achieve sum or difference frequency combining. Our team can provide standard products with a frequency shift of 20-300MHz, many of which can be implemented in dual crystal devices. The frequency shifter employs tellurium oxide with high acousto-optic merit (TeO CO₂),TeO CO₂ all of them are internally grown and Polishing processed by Fujing, which can ensure low insertion loss and high damage threshold. We can customize the center frequency and frequency shift of the product according to customer requirements. At the same time, Fujing can provide AOFS matching series RF variable frequency drive, according to the product specification to select the corresponding RF driver.
