  • Analytical strong-signal analysis for two-mode operation of homogeneously broadened lasers

    Publication Year: 1978, Page(s):325 - 327

    A strong-signal semiclassical analytical solution is obtained for a homogeneously broadened laser operating in two modes. The time development of the electric field is presented in a form similar to the weak-signal expressions of Lamb but with a modified description of the self-gain saturation coefficient β. The analysis favorably predicts the linearity of the output power of a laser gyro wit... View full abstract»

    The performance of a convenient cell for angle tuning of nonlinear optical crystalS, in which the crystal is rotated inside an index matching fluid, is described. Using a new fluid, the cell greatly reduces beam deviation, astigmatism, and transmission loss. View full abstract»

    Experimental data and the results of detailed numerical calculations are presented for small scale beam breakup due to non-linear self-focusing in Cyclops, a high power Nd-glass laser amplifier. Both perturbed plane wave and nonlinear whole beam calculations were carried out. The whole beam calculations were carried out using a dust particle model of beam perturbations. View full abstract»

    The population densities of the He(I) 2^{3}S and 2^{3}P levels and the Cd(II) ground level were experimentally determined with the modified absorption method in a positive column He-Cd laser discharge with little iodine. The population densities of the upper and lower laser levels of the Cd(II) 441.6 nm line were also ob... View full abstract»

    This paper considers the problem of forward Raman scattering process in a single transverse mode fiber. Both pump wave depletion and spontaneous scattering are considered in the analysis. Analytic solutions of the governing differential equations are obtained. We examine the conditions under which a nondepleted pump approximation is valid. Expressions are derived for the maximum fiber loss and the... View full abstract»

  • Low-loss Na-glass waveguides

    Publication Year: 1978, Page(s):323 - 325

    A new method for the fabrication of low-loss Na-glass waveguides on SiO2has been found. The reglassification process has enabled us to reduce the scattering loss in the planar waveguide to less than 1 dB/cm and to obtain channel waveguide with 2 dB/cm attenuation by the lift-off method or by the direct laser writing method.

    A rate equation model for an optically pumped submillimeter gas laser by J. R. Tucker has been extended to account for the pump radiation traveling in both directions in the laser tube. Calculations have been carried out for the (v3= 1 → 1, K = 2 → 2, J = 12 → 11) transition in methylfluoride. Results on the small-signal gain, the saturated gain, the pump absorption, a...

    Gallium arsenide has been investigated as a waveguide-cladding material for use as a cutoff polarizer for integrated optics. Calculations show that a 20 nm thick film of GaAs can be used to select either the TM0mode or both TM0and TE0modes, while maintaining a guide attenuation of less than 100 cm-1. View full abstract»

    Output intensity noise spectra of semiconductor lasers coupled to optical fibers with end-butt joints are measured to show periodic peaks with a fundamental frequency decided only by the fiber length. The frequency is found to coincide with the reciprocal of the roundtrip time of the light beam in the optical fibers. View full abstract»

    The characteristics of a fast discharge HF chemical laser are described. A Blumlein pulse forming line is used with a resistive cathode (50 Ω . cm resistivity germanium). Uniform arc-free discharges have been obtained in gas mixtures of SF6/H2/Ar, SF6/C2H6/Ar, and SF6/C3H8/Ar with electrode separations up ... View full abstract»

    The exact equations relating the CW output power to the parameters of a homogeneously broadened laser with distributed loss and its cavity are analytically intractable. In their place, simple approximate expressions are derived which permit convenient evaluation of the laser parameters from output power measurements in cavities with variable coupling, and conversely, of the maximum available oscil...

    A detailed theoretical analysis of nonresonant third harmonic generation (THG) is given which includes the intensity dependent refractive indices of the nonlinear medium as an integral part. According to the third-order analytic solution, the maximum attainable conversion efficiency is only limited by a nonlinear parameter β which is essentially the ratio of the Kerr-constants and the third h...

    Inter/cross modulation levels occurring in signals from stripe-geometry (GaAl)As double-heterostructure diode lasers are investigated by computer simulation for the case of time-division multiplexed (TDM) pulse-analog modulation (PAM). It is shown that pulse-position modulation (PPM) is the preferred modulation scheme for high pulse rates, and inter/cross modulation levels are evaluated for the fo... View full abstract»
