Low-power N-type Acousto Optic Driver for 1064nm High Power Fiber AOM Series
An acousto-optic driver is a specialized radio frequency (RF) signal generator used to drive acousto-optic devices with an output power of around 2W. The driver generates an RF signal that stimulates ultrasonic waves in the crystal of the modulator and changes the refractive index of the acousto-optical medium, thus affecting the beam properties. The frequency and intensity of the RF signal directly affect the intensity, deflection Angle, or tuning degree of the beam. The driver has good heat dissipation capacity and temperature stability.
| Supporting drive | Model SGXXXX-33-N-ab offers functionalities for frequency shifting (Y) and modulation (T) of RF signals. Its operating frequency is denoted by “XXX”, while “33” specifies the RF output power. The package type is indicated by “N”. Power supply voltage options are 24V (1) and 12V (2). Finally, “D” represents digital TTL modulation and “A” represents analog modulation. | |||
