KD*P Pockels Cell

SKU: KDPM

Made from the highest-purity, strain-free, and highly deuterated Potassium Dideuterium Phosphate (KD*P) crystals, the KDPM series Pockels cells deliver exceptional optical damage resistance and long-term reliability. For demanding environments, an index-matching oil immersion version is available to enhance stability under harsh conditions. The KDPM series comes in three aperture sizes: 8 mm, 10 and 20 mm. A compatible high-voltage pulse driver is available to support high-speed operation. The housing features standard pin-type HV connectors. For intensity modulation applications, polarization cubes can be aligned and mounted at the input and output ports. The voltage required to induce a π phase shift (Vπ) in the optical signal is given by the equation:where:
     λ is the wavelength of light,
     d is the electrode spacing,
     n is the refractive index of the crystal,
     r is the electro-optic coefficient,
     L is the crystal length along the light path.
The Vπ voltage is proportional to the wavelength and inversely proportional to the crystal length.
