1550nm Space AOM  Series

Spatial light acousto-optic modulators are used to modulate the intensity or frequency of a beam, with wavelengths ranging from the visible and infrared regions. The key parameter of the modulator is its rise/fall time, which determines the modulation speed or modulation bandwidth of the device to the beam. The product is packaged in a robust, all-metal housing that enhances the durability of the product for reliable operation in demanding environments. Innovative packaging technology further improves product reliability and temperature stability.

N-type Acousto Optic Driver

This dedicated acousto-optic driver module delivers tailored radio frequency (RF) signals for driving acousto-optic devices, including modulators and frequency shifters with drive requirements below 3 watts. Featuring precise RF generation, the module effectively excites ultrasonic waves within the device’s crystal, enabling control over the optical beam’s modulation, deflection, or tuning. Its design prioritizes efficient heat dissipation, and matched driver-device configurations further enhance temperature stability for reliable operation.
