Low-power N-type Acousto Optic Driver for 550nm High Power Fiber AOM Series
An acousto-optic driver serves as a dedicated radio frequency (RF) signal generator crafted for propelling acousto-optic devices, boasting an approximate output power of 3W. This driver initiates an RF signal stimulating ultrasonic waves within the modulator’s crystal, thereby altering the refractive index of the acousto-optical medium, consequently influencing beam characteristics. The frequency and intensity of the RF signal directly impact the beam’s intensity, deflection angle, or tuning degree. The driver ensures reliable performance and is equipped with efficient heat dissipation capabilities and temperature stability.
