780nm Fiber AOM Series

2000nm Fiber AOM Series

The acousto-optic modulator utilizes the acousto-optic effect to manipulate laser light. This effect allows for modulation of the light’s intensity and shifting of its frequency. The modulator operates across the spectrum, from visible light to infrared wavelengths. Its robust design features an all-metal construction, a compact and hermetically sealed package, and advanced packaging technology. These features combine to ensure exceptional reliability and thermal stability.

N-type Acousto Optic Driver

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.

Supporting DriveThe SGXXXX-33-N-ab model offers two functionalities: X indicates its ability to shift frequencies, while T signifies its modulation capability. The XXX represents the operating frequency, and 33 specifies the RF output power. The letter N denotes the package type. Power supply options are 24V (marked as 1) and 12V (2). Finally, D signifies digital TTL modulation capability, while A indicates analog modulation.
