POCKELS CELLSULTRAFAST PULSE PICKER – UP2|
HV POWER SUPPLIES

UP2 pulse picker consists of built-in drivers,
Pockels cell, high contrast ratio polarizers,
beam dump and other optical components
necessary for pulse picking application. The
UP2 pulse picker in setup with pMaster 4.2

POCKELS CELLS DRIVERS

Pulse picking rate up to 2 MHz

generator is able to select pulses at up to2 MHz rate from max 100 MHz repetition
rate pulse train. UP2 comes with BBO or KTP
Pockels cell which are set for quarter wave orhalf wave voltage operation depending on
the laser wavelength and required minimal
clear aperture of the Pockels cell.
KTP Pockels cell’s usage is limited by theaverage power of the laser beam – up to 2 W
and contrast ratio is typically >1:500. WhileBBO Pockels cells operate at much higher
power levels and feature higher contrast
ratio – typically >1:1000.
