    The operating characteristics of a neutral copper laser oscillating on the 5106 Å transition employing copper acetylacetonate, copper (II) acetate, and copper chloride oscillating on the 5106 and 5782 Å are described; and all three laser systems are compared in a fixed parameter system. The total output energies for optimum temperature, buffer gas pressure, dissociation pulse energy, and... View full abstract»

  • Modes of a symmetric slab optical waveguide in birefringent media - Part II: Slab with coplanar optical axis

    We study the modes of a symmetric thin-film slab waveguide composed of birefringent crystalline material in the film and in the equivalent substrate and superstrate. In addition we assume that the optical axes of the uniaxial materials of film and substrate are parallel to each other and also parallel (coplanar) to the plane of the film. This simple anisotropic waveguide has interesting properties... View full abstract»

  • Very high resolution CARS spectroscopy in a molecular beam

    Publication Year: 1979, Page(s):63 - 65

    Signal-to-noise calculations are presented for coherent anti-Stokes Raman spectroscopy (CARS) in a molecular beam. Using high peak power pulsed lasers and a high density molecular beam, S/N for the H2Q(1) line is expected to be \sim 10^{4} , with a Doppler width reduction from 1100 to 20 MHz. View full abstract»

    We show that one can generate the time-reversed replica of an "input" monochromatic, image-bearing beam by coupling it into a waveguide where it interacts with counterpropagating multimode "pump" waves of the same frequency. The nonlinear electric polarization density that is third order in the propagating electric fields in the guide medium generates the replica by the process of "four-wave mixin... View full abstract»

    The radiative lifetime of the blue C \rightarrow A transition of XeF has been measured to be 93 ± 5 ns by monitoring the exponentially decaying 460 nm emission following rapid electron impact dissociation of XeF2. By varying the XeF2partial pressure, the rate constant for quenching of XeF ( ... View full abstract»

    A more than 50 percent high power coupling efficiency has been demonstrated between a multiheterojunction GaAlAs LED (MH LED) and a taper-ended fiber. Optical power values coupled from the MH LED into a Corning silica fiber [numerical aperture (NA) = 0.18] and a Toshiba multicomponent glass fiber (NA = 0.27) were 360 and 560 μW, respectively, at 100 mA drive current.

  • Optical multistability in the mirrorless electrooptic device with feedback

    Publication Year: 1979, Page(s):82 - 85
    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (392 KB)

    Optical multistable operations are controllably accomplished in the mirrorless electrooptic device with feedback by arranging the polarizer and/or analyzer at appropriate angles with respect to the crystallographic axes of an electrooptic crystal. Moreover, different operating characteristics in two optical output powers with orthogonal polarizations separated from each other by an analyzer are ex... View full abstract»

  • Low absorption n-type gallium phosphide monitors for the HF laser

    The design of low absorption on-line monitors for HF laser radiation is presented. The detection process is optical rectification in n-type gallium phosphide. It is shown that a single plate of gallium phosphide can be used as both the output coupler and a power measuring monitor for HF lasers. View full abstract»

  • Improvements of a CO2-needle laser

    A disadvantage of pin lasers is often the bad quality of the laser beam. One aim of this investigation was the improvement of the beam divergence by an irregular arrangement of the needles in the cathode. In addition, the influence of a preionization was studied and the laser output is qualitatively compared with that of a UV-preionized one. View full abstract»

  • Limitations and optimization of (near) two-photon-resonant frequency up-converters

    Publication Year: 1979, Page(s):110 - 118
    Cited by:  Papers (13)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (888 KB)

    This paper considers the limitations of (near) two-photon-resonant frequency up-conversion due to quadratic Kerr effect, two-photon absorption, and Raman scattering. These processes, which are intimately tied to the four-wave mixing process, limit the efficiency and/or the pulse length due to breaking of phase-matching, attenuation, and (de)focusing. General expressions are derived for the limits ... View full abstract»

    An integrated optical circuit containing a laser, passive waveguide, and extra-cavity detector is described. These devices are fabricated from AlxGa1-xAs layers grown by liquid-phase epitaxy. Reflectors are formed by a two-step preferential etch procedure. For proper laser orientation on {100} wafers, the mirrors are found to be oblique, tapered so as to enhance coupling into...
