Pockels cell

[′päk·əlz ‚sel]
(optics)
A crystal that exhibits the Pockels effect, such as potassium dihydrogen phosphate, which is placed between crossed polarizers and has ring electrodes bonded to two faces to allow application of an electric field; used to modulate light beams, especially laser beams.

Its other principals are ULO Optics Ltd, the largest European IR optics manufacturer for laser and night vision optics, and Adamietz Electronics, supplying Pockels cell drivers for fast optical switches.
ii lot - nonlinear crystals: standard nonlinear crystal (bbo (bab2o4) dkdp (kd2po4) ktp (ktiopo4), lbo (lib3o5)) and non-standard nonlinear crystals that their physical size is different from the standard and fall or can be assigned in accordance with the intended purpose of use in any of the following groups: nonlinear crystals, pockels cells.
Upstream of the sample, the Pockels cells synchronized with the sweeping of the mirrors allow to deviate part of the beam in a given window.
