Welcome

QUBIG GmbH offers a line of highly efficient electro-optic modulators (EOM) mainly for applications in laser spectroscopy and frequency stabilization for laser cooling. Our resonant high-Q electro-optic modulators provide exceptional ease of handling and require remarkably low radio-frequency (rf) drive power. The output power of a regular VCO/function generator is typically adequate, thereby eliminating the need for costly high-voltage drivers. These state-of-the-art EOMs are designed by and tailored for researchers working with optical setups requiring a straightforward device to create sidebands for frequency locking techniques.
