FIELD: physics.
SUBSTANCE: essence of the invention consists in cooling the electro-optical element of the Pockels cell made of a DKDP crystal to cryogenic temperatures in an optical cryostat. To this end, the electro-optic element is connected by a heat-conducting ceramic plate to the cooling element and placed in an optical vacuum cryostat.
EFFECT: decreasing the optical power of the thermolens occurring in the device and reducing the control voltage of the device.
