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.
Optical power handling depends on the clear aperture size and the electro-optic (EO) material selected. Aperture size and crystal length dictate the required drive voltage. Compatible drivers are available on our website. For high-speed modulation, acousto-optic modulators (AOMs) should also be considered.
