FREE-SPACE ELECTRO-OPTIC MODULATORS

Electro-optic Modulators

Our Free-space Electro-optic modulators (EOMs) are efficient, convenient and easy to use tools to modify the phase, frequency, polarization or amplitude of a free-space laser. The modulation spectrum ranges from DC-coupled phase shifters to high-Q, resonant enhanced EOMs in the kHz, MHz and GHz range.

Large apertures and a large range of selected crystal materials (AR-coated or Brewster-cut) permit the use of high power lasers at UV to IR wavelengths with high optical transmission and low wavefront distortion.
