    We derive the nonlinear wave equation for an envelope of an electromagnetic wave in a monomode dielectric waveguide. Concrete examples are given for a single-mode optical fiber where the coefficients of resultant nonlinear Schrödinger equation with higher-order dispersion and dissipation (both linear and nonlinear) are given in terms of properties of the eigenfunction of the guided wave as we...

    A new method is proposed to achieve XUV generation in an He-K mixture medium excited by an electrical discharge by means of a double stimulated Raman scattering (SRS) process. First a dye laser of 404 nm radiation is down-converted tolambda_{s} = 1.209 mum in a Stokes SRS and then the produced IR radiation is up-converted tolambda_{as} = 64nm in an anti-Stokes SRS. The overal... View full abstract»

    A fully quantum mechanical theory of diode mixers which includes quantization of the external circuit is presented. We find that Tucker's theory for SIS mixer conversion efficiencies is correct, but that his expression for the measurement noise must be augmented by an amount corresponding to half a photon at every frequency to which the mixer responds. Noise in high quality SIS mixers is shown to ... View full abstract»

    A theory for strongly coupled waveguides is discussed and applied to two- and three-waveguide couplers and optical wavelength filters. This theory makes use of an exact analytical relation governing the coupling coefficients and the overlap integrals. It removes almost all of the constraints imposed by a simpler and approximate coupled-mode theory by Marcatili. It also satisfies the energy conserv... View full abstract»

    The role of the Zeeman effect for the power enhancement of a small-bore argon ion laser (488.0 nm) by applying the transverse magnetic field has been investigated both experimentally and theoretically. The σ-polarized laser has a larger output power than the π-polarized laser in the wide range of magnetic field strength. Specifically, at weak magnetic fields, enhancement occurred only fo...

    We apply a formula for the small signal gain of a dye laser amplifier (obtained and verified in a previous work) to the case of a transverse pumped R6G amplifier. We trace a set of curves as a function of dimensionless parameters which give the gain for any combination of the parameters characterizing the amplifier (dye concentration, active length, etc.). The curves can be applied to design dye l... View full abstract»

    The refractive-index profile of dual-mode optical fibers which makes possible dispersion-free operation at 1.55 μm wavelength is proposed. The refractive-index profile is synthetized using methods of quantum mechanics and numerical procedure. Optical fibers with this refractive-index profile have a core diameter of about 23 μm that is much larger than the core diameter of conventional si... View full abstract»

    The saturated absorption spectra and line widths of the Cs-D2line were observed as a function of the incident power. A minimum spectral width of 20 MHz was obtained when the incident power was under 0.1 mW and all of the hyperfine spectral lines and the cross-over resonance lines were resolved. View full abstract»

    The theory of broad-band forward Raman amplification is presented. An exact solution for the pump and Stokes fields is derived in the limit of negligible population transfer, negligible linear dispersion, an arbitrary number of axial modes with mode spacing much larger than the Raman linewidth, collimated-beam ray optics, and arbitrary Raman conversion. It is shown that if the incident pump and St... View full abstract»

    The characteristic modes of coupled waveguide arrays with a simple layered structure are examined using the approximate coupled wave theory. It is shown that evanescent waves may arise from total internal reflection at a boundary between two semi-infinite arrays. The transmission and reflection coefficients for this process are derived. If a suitable, finite, array is sandwiched between two semi-i... View full abstract»

    A new model for the inherent electrical state of the tandem laser is presented. The electrical coupling between the sections is known from experiments to have a large impact on such a laser. In contrast to earlier rate-equation analysis, our new model allows for an investigation of this influence. In this paper we present results from a theoretical study of how the bistability depends on various p... View full abstract»

    The Hermite-Gaussian periodically focusing beam solutions of the scalar paraxial wave equation with quadratic index variation are appropriate for rectangular coordinates. One expects the solutions appropriate to cylindrical coordinates to be LaGuerre-Gaussian multifocusing beams. The phase shifts of these solutions appear not to be available in the published literature. In this note, we present an... View full abstract»

    High average power frequency conversion using solid-state nonlinear materials is discussed. Recent laboratory experience and new developments in design concepts show that current technology, a few tens of watts, may be extended by several orders of magnitude. For example, using KD*P, efficient doubling (> 70 percent) of Nd:YAG at average powers approaching 100 KW is possible; for doubling to th... View full abstract»

    The complex eigenvalue equations of metal-clad graded-index waveguides are generally solved by numerical methods. The role of waveguide and material parameters in determining mode dispersion and attenuation becomes difficult to elucidate. We describe a perturbative method of solution which is suited to the class of waveguide in which the guided field is described analytically. Mode dispersion and ... View full abstract»
