EO-BBL

wideband, multi-octave electro-optic phase modulator (EOM) designed for phase-shifting applications (lock signal tuning) specifications: f ∼ 5 − 50MHz, max. rf power 1/4W, β ∼ 0.15 rad/V

Any qubig EOM can be customized in the frequency range from 5MHz − 2GHz. Available options include mechanically tunable resonance frequency, increased optical damage threshold, higher rf-power rating, and different anti-reflection (AR) coatings (vis 400 – 700nm, nir 650 – 950nm, ir 950 – 1500nm, up to 3μm). Modifications of the housing, rf-connector, electro-optic material, and crystal size can be accommodated according to customer requirements.(contact)
