Low-power N-type Acousto Optic Driver for 1650nm Fiber AOM Series
An acousto-optic driver is an electronic device that generates radio frequency (RF) signals to control acousto-optic devices, such as modulators and frequency shifters, requiring less than 3 watts of power. Piezoelectric transducers convert radio frequency electrical signals into ultrasonic signals. By adjusting the frequency and strength of the RF signal, the driver can precisely control the modulation, deflection, or tuning of the laser beam. The drive effectively dissipates heat for reliable operation, and the use of matching drives further increases temperature stability.
| Supporting Drive | The model designation SGXXXX-33-N-ab provides a concise overview of its key specifications: Function: “X” signifies its ability to shift the frequency of light, while “T” indicates its modulation capability, allowing for intensity control of the laser beam. Operating frequency and power: “XXX” represents the specific frequency at which the driver operates, while “33” specifies the radio frequency (RF) output power. Package type: “N” indicates the physical package style of the driver. Power supply: “A” with options “1” and “2” correspond to power supply voltages of 24V and 12V, respectively. Modulation type: “b” with options “D” and “A” specify whether the driver supports digital TTL modulation or analog modulation for controlling the laser beam. | ||||||
