Low-power N-type Acousto Optic Driver for 2000nm Fiber AOM Series
The acoustooptic driver is an electronic device that generates radio frequency (RF) signals to control acoustooptic devices, including modulators and frequency shifters, requiring less than 3 watts of power. These RF signals trigger the generation of ultrasonic waves within the device’s crystal. By adjusting the frequency and intensity of the RF signal, the driver can precisely control three key aspects of the laser beam: modulation (intensity control), deflection (direction control), and tuning (frequency control). The driver is equipped with efficient heat dissipation for reliable operation, and using a matched driver further improves temperature stability, ensuring optimal performance.
