    We propose a new way of making highly resonant integrated optical circuits based on weak side-by-side coupling between waveguides and highQdistributed Bragg resonators. This method can be used to design a resonant optical reflector which, when used as a feedback element to a laser, will result in a compact structure that has both extremely narrow line width and very low chirp.

    A microwave field can be used to accelerate electrons as they lose energy to radiation in an FEL, thereby maintaining synchronism and, used in conjunction with an optical klystron, providing high conversion efficiencies. The microwaves can be programmed to increase in time with the optical power level in the FEL so that high gain is maintained over a wide range of power levels. In this paper, para...

    We explore the possibility of using a relativistic plasma density wave as a wiggler for producing free-electron laser radiation. Such a wiggler is a purely electric wiggler with frequency ωp(plasma frequency) and wavenumber kp. If an electron beam is injected parallel to the plasma wave wavefront, it is wiggled transversely with an apparent wiggler wavelengthlambda_... View full abstract»

    Coherent electromagnetic radiation from a thin rotating annular ring of relativistic electrons with axial drift, and confined between concentric cylinders comprising a coaxial waveguide, is studied theoretically. The electrons are assumed to move in quasihelical orbits under the combined action of a uniform axial magnetic field and an azimuthally periodic wiggler magnetic field. The instability an...

    We discuss the possibility of building a free-electron laser in the spectral region of tens of nanometers using a high-power laser pulse as the undulator. Requirements on the electron beam emittance, brightness, and energy spread are derived. The possibility of operation at the quantum limit is considered. The reduction of the gain due to diffraction of the undulator pulse (the variable mass-shift... View full abstract»

    The Madey theorem has been used to calculate the small-signal gain of a planar magnetic wiggler FEL and optical klystron. The analysis in this paper shows that the Madey theorem can also be applied to media FEL's, i.e., Cerenkov and transition radiation FEL's, as well as electrostatic FEL's. Here we use the Madey theorem to calculate the small-signal gain of these two kinds of FEL's. View full abstract»

    The conventional free-electron laser small-signal linear gain equation is revised to include the effects of nonuniform optical mode area, finite electron beam emittance, and electron beam energy spread. It is shown for a typical case that the conventional equation overestimates gain by more than 50 percent. The results further show that gain can result from FEL designs with interaction lengths lon... View full abstract»

    The nonlinear motion of electrons in a quadrupole free-electron laser is analyzed. If the betatron frequency is close to the mismatch frequency, the three-dimensional nonlinear equations can be reduced to an integrable one-dimensional equation. To enhance the efficiency, a tapered wiggler is introduced and the electron orbits in a tapered quadrupole free-electron laser are analyzed. The conditions... View full abstract»

    We have demonstrated for the first time a resonant optical reflector having a reflection resonance less than 2 Å wide. This reflection is formed in a waveguide weakly coupled side by side to a quarter wave shifted Bragg resonator. We also present an experimental and theoretical study of the transmission spectra of such a resonator. In all cases, the experimental spectra are in good agreement ... View full abstract»
