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.

Incident laser intensity was manually adjusted via a Pockels cell in the excitation pathway.
INVESTIGATION OF POCKELS CELLS CRYSTAL CONTRAST RATIO DISTRIBUTION
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.
This artificially created crystal has a large electro-optic and acousto-optic coefficient, and as such it is a favoured material for a number of non-linear applications; Q-switches, Pockels cells, phase modulators and waveguides.
