Abstract
An original and reliable technique, based on a three-wave interaction, has been designed and successfully tested to analyze the evolution of the modes and the pulse length of a free-electron laser during the buildup of the radiation. The technique was developed in order to study the effects of the optical guiding in the free-electron laser built at Stanford and driven by the MARK III linear accelerator. We explicitly mention that this technique can be easily exploited to monitor, in real time, the pulse-to-pulse fluctuations of the mode size and the pulse length of the pulses delivered by any laser independently of its pulse length from femtosecond to millisecond.Keywords
