POCKELS CELLSPULSE PICKER – MP1|Features

POCKELS CELLS DRIVERS

Pulse picking rate up to 600 kHz
Fast Amplitude Modulation version
available|

MP1 pulse picker consists of built-in fast
driver and a Pockels cell. This unit is able toselect pulses at up to 600 kHz rate. MP1 isoperated by pMaster 4.2 generator which
provides sync pulses for driver control andhas built-in HV power supply. MP1 can besynchronized with a laser generating pulse
train with max 60 MHz repetition rate forsingle pulse picking task when it is in setup
with pMaster 4.2 generator.

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 MHzgenerator 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 or
half 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 Wand contrast ratio is typically >1:500. WhileBBO Pockels cells operate at much higher
power levels and feature higher contrast
ratio – typically >1:1000.
