High-Q Light Modulators

Since 2008 QUBIG GmbH develops and manufactures cutting-edge Light Modulators for scientific and industrial applications. A large frequency range, outstanding modulation efficiency and selected crystals make the modulators suitable even for single-Photon and high-power cw laser applications from UV to MIR.

EMPOWERING LASER TECHNOLOGIES

QUBIGs high-tech devices are mainly implemented as additional modules in larger laser systems for controlling and precisely manipulating the properties of laser light, such as its frequency, phase, polarization and position. The high quality combined with exceptional broad parameter ranges make our products very versatile and thus useful to a broad range of applications such as Laser frequency stabilization (FM-/MT-spectroscopy, Pound-Drever-Hall),

Interferometry, Laser cooling of neutral atoms and ions (Repumper generation, Magneto-optical trap), Optical pumping (Laser Guide Star), Spectral broadening (Reduction of Stimulated Brillouin Scattering SBS, White MOT), Quantum computation and cryptography (Paul trap, NV centers, Quantum dots) and Laser material processing (Q-Switch, Optical chopper, Multiplexer, Mode Locker).

Modulation Frequency

DC/HV – 20GHz

QUBIG GmbH offers DC-coupled, broadband electro optic phase and polarization shifters as well as high efficient, resonantly enhanced phase and amplitude modulators up to 20GHz.

Spectral Range

UV - MIR

Our extensive knowledge about crystal optics and longstanding experience with a variety of materials enables QUBIG to provide modulators for the entire spectral range from 200nm to 12um.

Optical power Range

kW – ℏω

Excellent optical quality and high transmission make our modulators suitable for single-photon experiments as well as high power applications like Laser Guide-Stars or intra-cavity systems.
