Pulse Picker MP1

Pulse picker MP1 consists of built-in fast driver and a Pockels cell. This unit is able to select pulses at up to 600 kHz rate.


MP1 requires sync pulses from the laser for driver control or can be used with pMaster 4.0 generator. In setup with pMaster 4.0H generator can be synchronized for single pulse picking from max 30 MHz repetition rate pulse train.


MP1 pulse picker has BBO Pockels cell and is set for quarter wave voltage operation. On special requests BBO cell can be changed to KTP Pockels cell for half wave voltage operation.
