Electro-Optic Modulator M380
All Conoptics electro-optic modulators use a transverse field perpendicular to light propagation. Multiple system configurations optimize applications. Crystal length/aperture ratio adjusts half-wave voltage, a key configuration factor. Half-wave voltage scales with wavelength, so longer-wavelength devices generally need higher ratios to match existing driver levels. ADP (NH4H2PO4), KD*P (KD2PO4) and LTA (LiTaO3) offer advantages such as low piezoelectric effects or lower half-wave voltage for high-performance lasers. Referenced specifications cover ADP 240–800nm, KD*P 240–1100nm and LTA 700–2000nm. Conoptics pulse-picking systems reach 100MHz, transmission >85%, minimum pulse width 18ns, no spatial dispersion or lateral output-beam shift, and 350–1600nm coverage.
