Abstract
Coherent Photon Seeding (CPS) has proven to be a powerful and simple technique to stabilize synchronously pumped mode locked (SPML) lasers.[1-5] The idea of this technique is to apply a very weak coherent feedback (typically 10-8 of the laser output) - e.g. from a linear external cavity - in order to suppress the deleterious influence of spontaneous emission which is responsible for the usually observed large energy fluctuations of SPML lasers.
