QDSM Series Q driver is a low to medium power RF generator used to drive picosecond lasers, short pulse laser amplification stage acousto-optic Q switches, of course, can also be used in other radio frequency fields. QDSM Series Q drive has compact structure, stable RF output, strong anti-interference ability, high reliability, and is an acousto-optic Q switches.

this series Q drive model naming rules are as follows:
QDSMxxx-yyW-zzV-aaa
- xxx: output frequency, unit MHz; optional values: 041(40.68MHz), 068(68MHz), 080(80MHz).
- yy: RF Rated output power, unit W; for example: 20. 2~24W.
- zz: DC supply voltage, unit V; optional values: 12, 15.
- aaa: Factory default compression mode(Dial code adjustable); optional values: R05, A05.
for example: QDSM080-15W-15V-A05, that is, the output frequency 80MHz, rated output power 15W, 15V powered, the factory default compression mode is A05.
