QUBIG GmbH specializes in design and manufacturing of world-class electro-optic modulators (EOM) for scientific and industrial applications requiring optical sidebands on free space lasers. Large apertures, outstanding modulation efficiency and selected crystals make our EOMs the right choice even for high-power lasers from UV to IR wavelengths. Available in quick delivery standard models and challenging custom developments.


Key Features Applications
  • high-Q resonance [0.1MHz - 3 GHz] - fixed or tunable
  • great modulation efficiency - low rf drive power
  • low residual amplitude modulation (RAM)
  • high power versions from UV - IR
  • optical cavity / laser frequency stabilization - PDH locking
  • laser spectroscopy - frequency modulation (FM)
  • laser cooling repumper generation
  • spectral broadening
