    An experiment has been performed to demonstrate a third-order nonlinear optical effect involving the ground state of the strontium ion. Evidence of strong and slightly tunable parametric generation from a doubly resonant four-wave mixing process is provided when a single-wavelength laser is used to two-photon ionize strontium vapor and simultaneously pump close to the View full abstract»

    We present a theory of adiabatic chirp reduction and narrowing of the Lorentzian laser line that occurs when a laser is coupled to an external passive resonator. Chirp reduction and line narrowing are simply related. We show that the reduction in the Lorentzian line width is equal to the square of the reduction in adiabatic chirp. Both are strongly enhanced near resonances of the external cavity. View full abstract»

    A scheme for efficiency enhancement in free-electron lasers which are driven by electromagnetic-wave wigglers is described which employs a tapered axial guide magnetic field. While tapered magnetostatic wiggler designs have been proven to be an effective means of enhancing the efficiency of free-electron lasers, practical difficulties occur in the design of tapered electromagnetic-wave wigglers.

    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»

    The mode analysis of an open-boundary Cerenkov laser is developed in the collective regime. The Cerenkov laser under consideration consists of a relativistic slab electron beam and a dielectric-loaded conducting plane. The beam and the dielectric are assumed to be arbitrary in thickness, with an arbitrary gap allowed between them. For the Cerenkov laser specified above, the dependence of the growt...

  • Effect of electron beam temperature on the gain of a collective free-electron laser

    At sufficiently low beam currents, electron beam temperature effects cause the gains of collective (Raman) regime free-electron lasers to be lower than the predictions of cold beam theory. This gain degradation has been measured as a function of the beam current, the wiggler magnetic field, and the interaction frequency. The measurements are used to estimate the electron beam temperature, and the ... View full abstract»

    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»

    In this paper, we review the most recent experimental results of the Los Alamos free-electron laser program. Three major efforts will be described: lasing at improved efficiency over that previously attained, electron beam improvement, and energy recovery. An extraction efficiency of 2 percent was achieved with a wiggler having a 12 percent wavelength taper. The beam has been improved so that limi... 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 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 wavelength ... View full abstract»

    Harmonics are generated in free-electron lasers as a result of the nonuniform axial motion of the electrons. These motions can be manipulated through the addition of harmonic wiggler fields. A mathematical formalism is developed that describes the effects of harmonic wiggler fields on the fundamental and harmonic coupling coefficients. An examination of how these fields can be used to alter the ha... View full abstract»
