QDS Series Q driver is a low-to-medium power RF generator used to drive end pumps, side pumps and other types of lasers, but can also be used in other RF fields. QDS Series Q driver has compact structure, stable RF output, strong anti-interference ability, high reliability, and has a variety of suppression modes for the first pulse, which is acousto-optic Q switches.
Model Definition
this series Q drive model naming rules are as follows:
QDSxxx-yyW-zzV-aaa
- xxx: output frequency, unit MHz; optional values: 041(40.68MHz), 080(80MHz).
- yy: RF Rated output power, unit W; for example: 20. 5~20W.
- zz: DC supply voltage, unit V; optional values: 12,15.
- aaa: Factory default compression mode(Dial code adjustable); optional values: FPS, PPK.
Model example:
QDS041-20W-15V-PPK, that is, the output frequency 40.68MHz, rated output power 20W, 15V powered, factory compression mode is PPK.
