Pulse Picker is a synchronization tool to drive external modulating devices such as EOM, AOM, SOA etc.  It has been designed to work with low level electrical or optical input pulse power. It includes 3 pulse picking modes (frequency divider, external  triggering & high frequency clock, burst shaping) : see the detailed application note : Pulse-Picker

This Pulse Picker board includes a software adjustable input voltage level threshold and a photodiode (optional). This board also includes a special AWG function synchronized with the input signal to perform some Burst Shaping of mode-locked lasers.

Pulse picker Key features :

pulse picker
This product has a small form factor and an easy-to-use GUI
  • 1V/3.3V/5V output voltage
  • Min input voltage: < 30 mV
  • <80 ps RMS jitter
  • Max Input frequency : 200 MHz
  • Max output frequency : 20 MHz
  • 3 modes : Divider (low Jitter), Synchro (external) and Burst shaper
  • USB interface with many Libraries and GUI

 

This  Pulse Picker  works alone or in series with other products in our range like :

 

The GUI software lets the user have total control of all module functions. It includes several libraries for software integration (LabVIEW VIs, DLLs, Hexa, Python etc.). Complex systems, such as fiber lasers, can be quickly developed on this module platform.

This pulse-picker board is part of our “Multiboard” laser driver and synchronization modules family. It works perfectly well to synchronize any AOM devices, for example Brimrose or Gooch and Housego. All the using cases are explained in a well detailed Pulse picker Operating_manual and a specific application note.
