Q - DRIVERS | RF Drivers for High-Q Resonant Modulators

QUBIG offers dedicated RF drivers which match and enhance the features of all free-space modulators. Digital frequency synthesis allows precise frequency and phase control. An integrated EOM lock (Q-Lock) working up to 20GHz automatically finds and subsequently tracks the resonance frequency of the modulators which ensures an operation at optimal efficiency. Together with the automatic frequency drift compensation (F-Lock) QUBIGs RF drivers have become a plug & play system where only two input parameters are required: the desired frequency and modulation depth.

The QDR-series  can optional be equipped with a heterodyne frequency mixing circuitry for the error-signal generation of all common methods used in laser frequency stabilisation techniques such as Pound-Drever-Hall (PDH), Frequency Modulation (FM) as well as Modulation Transfer Spectroscopy (MTS) with full digital phase control and neat features like 3ω-mixing for active RAM suppression. Easy system integration and implementation is assured by various interfaces for external control and interlock. All devices can be used via a customer friendly front panel.
