    A thermally tuned Q -switched ruby laser of moderate power, with emission wavelength at 6939 Å, has been used to selectively excite the 4^{2}P_{3/2}-6^{2}S_{1/2} transition in the atoms of a pure potassium plasma of low degree of ionization produced in a hot cathode diode. A pulse of intensified spontaneous emission ha... View full abstract»

    The details of the analysis, design, and operation of a Nd-glass-disk-laser amplifier which has been constructed at the Naval Research Laboratory are presented. Gain and fluorescence measurements have been compared to theoretical predictions; these show that 0.6-J/cm3energy storage is achieved in the disk (assuming a cross section of ... View full abstract»

    Frequency characteristics of a nonlinear lasing gain under the condition that a laser oscillation exists at a fixed frequency are theoretically obtained on the basis of a band-to-level transition model (without the k - selection rule) of semiconductor lasers. This nonlinear gain exhibits a spectral hole-burning in the vicinity of oscillation frequency as well ... View full abstract»

    Vacuum ultraviolet emission from high-pressure Xe gas under excitation by a pulsed electron beam has been investigated. When cavity mirrors were provided, significant line narrowing and a thousandfold increase in spectral intensity occurred at 1730 ± 10 Å. This was accompanied by severe mirror burning and provides strong evidence that an associative molecular Xe laser has been achieved. View full abstract»

    An optical modulator having a bandwidth of 1.6 GHz and a required power of 1 W for 100-percent intensity modulation at the wavelength of 0.63 μm has been constructed. The wide-band and low-drive power performance is obtained by the use of a structure-like beam waveguide. View full abstract»

    The properties of AlxGa1-xAs heterojunction incoherent edge emitters are described. Single (SH) and double-heterojunction (DH) diodes emitting at about 8200 Å were studied. The highest CW radiance measured perpendicular to the emitting facet was 95 W/cm2.sr at 4200 A/cm2for a stripe-geometry SH device. This high radiance level was found to be consis...

  • Oversaturation of high-gain CO2lasers

    Sophisticated numerical calculations have been made of the optical power densities available in electric CO2lasers. For high values of the vibrational temperature of the ν3mode (> 1000 K), they give values 25 percent lower than those obtained by the classical gain-saturation formula. This oversaturation effect may also exist in other types of lasers. View full abstract»

    A number of photoionization mechanisms and how they can be used to generate large-volume laser plasmas are discussed. Reaction rates for two-step photoionization of the cesium atoms as well as formation of molecular ions (Cs2+) are estimated. The necessary cross-section data were obtained from related research in thermionic energy converters. View full abstract»

  • TE modes of graded-index slab waveguides

    An analysis of the TE modes of a slab waveguide with graded refractive-index distribution is presented. The refractive index is approximated by a piecewise-linear distribution for which exact solutions of the guided-wave problem can be obtained. For multimode guides, useful approximate solutions can be worked out with the help of the Wentzel-Kramers-Brillouin (WKB) approximation. A formula is give... View full abstract»

  • Transmission of a kodak 9740 dye solution under picosecond pulses

    The transmission of Kodak 9740 dye solutions as a function of picosecond pulse energy has been measured. The experimental results have been compared to theoretical ones. The validity of these results is borne out by the variation of the round-trip transit gain in the train of pulses emitted by a Nd3+glass laser mode locked by a Kodak 9740 dye solution. On the basis of this last result, ... View full abstract»

    Properties of planar dielectric waveguides having a diffusion-induced index of refraction distribution are investigated. It is found that the spatial distribution of modes, group velocity, and mode spectrum of these guides differed qualitatively from the corresponding properties found in a slab waveguide. These results were experimentally verified by measuring the mode spectrum of a dielectric wav... View full abstract»

    The response of germanium photon-drag detectors at high CO2-laser intensities is found to be nonlinear. Depending on the conditions, both superlinearity and saturation can be observed. It is known that the absorption of germanium at 10.6 μm decreases at high intensities, while the resistivity increases. It is shown that the nonlinear behavior of drag detectors can be satisfactorily... View full abstract»

    Deformation of the spot of an off-axis Gaussian beam after passing through a lens-like glass fiber (SELFOC®) with the fourth-order aberration is investigated by using first-order perturbation theory and numerical calculation. A method for determining the coefficient of the fourth-order aberration is proposed. By this method, it is found that a SELFOC sample (0.5 mm in diameter and 150 mm in l... View full abstract»

    The spectrum of the light emitted at 10 200 Å by an NO laser is photographed with high resolution. The rotational analysis fully confirms the assignment made earlier to the transition F^{2}\Delta -C^{2}\Pi (1, 1) between two electronically excited levels of the NO molecule, both of which are configurationally mixed with valence levels.
