RF Driver

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 16GHz 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.

PREDEFINED RF DRIVERS - PRFD

From our general product series numerous predefined models has been derived to enhance the EOM performance and match the requirements for various applications in quantum science experiments like laser trapping and cooling of neutral atoms (ATC), ions (ITC), molecules (MTC) as well as optical clocks, spectral broadening (SB) and laser frequency stabilisation (LFS).
