    We describe a continuous tunable ultraviolet radiation source, operating in the spectral range 290-315 nm by intracavity frequency doubling of a rhodamine 6G dye laser. Maximum intracavity second-harmonic power of 1.1 mW was obtained at 296 nm with a bandwidth of 0.1 nm. View full abstract»

    Attenuation and phase constants are calculated for a metal-clad-dielectric-slab waveguide and the results show the behavior of the propagating modes as a function of cladding material and dielectric. Analysis indicates that the dielectric properties influence the attenuation and cutoff frequencies whereas the metal cladding influences primarily the attenuation of propagating modes. Variation of th... View full abstract»

    The production of uniform large-volume laser plasmas with electron-ion densities on the order of 1012/cm3or larger by means of photoionization is investigated. An externally applied electric field heats the electron gas to the optimal temperature for excitation of laser levels. Photoionization by intense UV light may take place in a low partial pressure gas of low ionization ... View full abstract»

    Hollow waveguide gas lasers of the type described by Smith have some inherent loss in coupling radiation from the guide into free space and back into the guide. This paper calculates that loss for the EH11lowest order waveguide mode as a function of mirror position and mirror radius. It is shown that some mirror positions and radii are optimum, in that they provide low coupling loss and... View full abstract»

    We have investigated some of the properties of distributed-feedback (DFB) lasers made in active thin-film optical waveguides. By optically pumping these guides with spatially modulated light we have obtained narrow-line tunable oscillation. Operation in single-mode waveguides is well behaved and understood. Measurement of the oscillating wavelengths can be used to determine accurately the paramete... View full abstract»

    Eighteen electrically pulsed parent compound-helium mixtures yielded N, C, Cl, or F atom lasing. The laser pulses appeared as one or more peaks at each wavelength. New lasing on the chlorine wavelength (3.5443 μmvac) was observed from a Cl2-He mixture. View full abstract»

  • Self-pulsing GaAs laser for fiber-dispersion measurements

    Internal self-pulsing of commercially available GaAs lasers produces pulses as short as 100 ps. The simplicity and versatility of such devices make them very useful for fiber-dispersion studies. We describe pulse-transmission measurements in 178 m of a liquid-core fiber and explain the considerable pulse broadening (11 ns at the pulse base) in terms of mode delay and mode mixing.

    It is shown theoretically that short intense light pulses of optical filaments can form an optical shock at the leading edge in the usual Kerr liquids. Under certain conditions an extremely sharp spike occurs at the front of the pulse. View full abstract»

  • Generation of single l-ns pulses at 10.6 µ

    Single pulses of 1-ns duration have been generated at 10.6-μ wavelength using a pulse-selection scheme in conjunction with an actively mode-locked CO2TEA oscillator. The experimental setup and its operating characteristics are presented. A technique is described, which yields pulse extinction ratios of approximately 900:1. View full abstract»

  • Fiber-dispersion measurements using a mode-locked krypton laser

    Mode delay and material dispersion limit the signal bandwidth of potential fiber communication systems. 200-ps pulses from a krypton laser, mode-locked at three different wavelengths, prove to be adequate for measuring both effects in relatively short fibers (33 m). The results are in good agreement with theory. View full abstract»
