A distributed trigger system for picosecond LASER facilities

The Commissariat a l'Energie Atomique (CEA) is developing a unique picosecond timing system for the Laser MegaJoule (LMJ) project which includes an original concept to trigger picosecond laser sources with ultra-low jitter. We present the concept and how it can be used to implement the LMJ optical fiducial system or to synchronize a picosecond X laser source. We expose achieved performances.
