High Q Light Modulators

QUBIG GmbH has developed and manufactured high Q Light Modulators for scientific and industrial applications

Electro-Optic Modulators

Our free-space electro optic modulators are user-friendly and effective tools that can be used to alter the phase, frequency, polarization, or amplitude of a free-space laser. The modulation spectrum includes DC-coupled phase shifters and high q, resonant enhanced EOMs that operate in the kHz, MHz, and GHz range.

The availability of a wide range of crystal materials (AR-coated or Brewster-cut) and large apertures enables the use of high power lasers at UV to IR wavelengths with minimal wavefront distortion and high optical transmission.
