Pockels Cells feature fast and precise control of the laser beam polarization direction as a function of applied voltage. High effective transmission, fast rise/fall time of the high voltage pulse, and high contrast ratio make Pockels cells the primary choice for pulse picking from the laser pulse trains emitted by high-power ultrafast lasers.
EKSMA Optics introduces special design BBO and DKDP (KD*P) Pockels cells for advanced control of high power laser beam polarization.
Quadruple BBO Pockels cell employs four electro-optical crystals with independent high voltage electrodes at two sides. This Pockels cell can be controlled by two HV drivers enabling advanced control of the parameters of laser pulses.

Enables sophisticated laser pulse polarization and amplitude control employing two high voltage drivers.
Shorter HV pulse rise/fall time due to lower operating voltage
