Product Description

Introduction 
The QDN series represents a newly designed, ultra-compact Q-switch driver featuring an open-frame construction. Compared to other products, it stands out for its reliability and cost-effectiveness. As a medium to low-power RF generator, the QDN series Q-switch driver is designed to drive end-pumped and side-pumped lasers, as well as find applications in other RF fields. The QDN series boasts a compact structure, stable RF output, strong anti-interference capabilities, and high reliability. Equipped with multiple suppression modes for the first pulse, it serves as an ideal driving source for acousto-optic Q-switches.
