Ultra-small pulse selection AOM driver
The QDR Series AOM Driver is a low-power RF signal generator, designed for driving acousto-optic modulators (AOMs) in picosecond short-pulse laser systems. It is ideal for pulse picking, AOM switching, Q-switched laser acousto-optic modulation, Fiber Q switches, and other RF-driven applications. The QDR Series AOM Driver features a compact structure, stable RF output, strong anti-interference capability, and high reliability, making it an excellent drive solution for acousto-optic modulators (AOMs).
