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.

    Periodical short pulse trains were observed in a long pulse, low current, low voltage waveguide mode free-electron laser. The pulse width and the pulse train intervals of the periodical short pulse trains were about a few ns and about 23 ns, respectively. These pulse trains can be explained as...

    Excitation of an obliquely propagating upper-hybrid cyclotron beat wave is considered for plasma heating and current drive in tokamaks. The beat wave is excited by the interaction of two intense free-electron laser (FEL) pulses at their difference frequency. The three-wave nonlinear interaction...

    A laser wakefield acceleration (LWFA) model has been upgraded to better predict the outcome of experiments to test two new LWFA techniques. The first method is seeded self-modulated LWFA where an ultrashort electron bunch acts as a seed to create a wakefield in a plasma, which is subsequently...

    Many scientific disciplines ranging from physics, chemistry and biology to material sciences, geophysics and medical diagnostics need a powerful X-ray source with pulse lengths in the femtosecond range [1-4]. This would allow, for example, time-resolved observation of chemical reactions with...
