1064nm Space AOM  Series

An acousto-optic modulator (AOM) is a kind of acousto-optic device that can modulate laser intensity and frequency shift by the principle of acousto-optic interaction. Its modulation bandwidth and dynamic range are much better than traditional mechanical products. Operating wavelengths extend from visible to mid-infrared. The rise/fall time of the light pulse is proportional to the beam diameter. Therefore, the laser beam must be focused inside the modulator to achieve a faster rise time. The product is packaged with a full metal shell, which is not easy to wear and has stable performance.

N-type Acousto Optic Driver

This acousto-optic driver module functions as a dedicated radio frequency (RF) signal source specifically designed to support acousto-optic devices. Compatible with acousto-optic modulators and frequency shifters requiring driving power below 3 watts, the module precisely generates an RF signal to excite ultrasonic waves within the device’s crystal. The applied RF signal’s frequency and intensity directly influence the beam’s modulation, deflection, or tuning degree. Notably, the driver boasts an efficient heat dissipation design, and implementing a matched driver-device combination enhances temperature stability.
