Low-power N-type Acousto-optic Driver
The low-power N-type acoustooptic driver is a dedicated radio frequency (RF) signal generator specifically designed for acousto-optic devices requiring less than 3 watts of driving power. This includes both modulators and frequency shifters. The driver generates RF signals that, when applied to the device’s crystal, create ultrasonic waves. By adjusting the frequency and intensity of these RF signals, the driver precisely controls the modulation (intensity), deflection (direction), and tuning (frequency) of the laser beam. The driver features efficient heat dissipation for reliable operation, and using the corresponding matched driver further enhances temperature stability for optimal performance.

| Supporting Drive | The SGXXXX-33-N-ab model offers two key functionalities: frequency shifting (“Y”) and modulation (“T”). Its operating frequency, represented by “XXX”, determines the RF output power, specified here as 33 dBm. The letter “N” indicates the package type. It supports power supply voltages of 24V (“1”) and 12V (“2”). Finally, “D” signifies digital TTL modulation capability, while “A” indicates analog modulation. | ||
