    A mathematical model utilizing two coupled anharmonic oscillators is applied to CdTe to predict its nonlinear susceptibility. Three of the four constants appearing in the model are determined from recent experimental data on electrooptic coefficients and second-harmonic generation in the region 3-28 \mu . The first-order nonlinear susceptibilities appearing i... View full abstract»

    This correspondence describes the concept of a non-reciprocal transmission isolator or four-port circulator consisting of an anisotropic index of refraction element inside the perimeter of a traveling-wave (ring) interferometer. The potential advantages of this device with regard to feedback power rejection capability and rejection ratio are discussed. View full abstract»

    Results on the simultaneous initiation of four high-voltage spark gaps by a single moderate power laser system are presented. A Q -spoiled YAG laser irradiated each of four 50-kV spark gaps with 10-20 mJ energy in a 7-ns pulse full-wave at half maximum (FWHM) by use of simple beam-splitting techniques. Synchronization of ∼ 0.1 ns at repetition rates as hig... View full abstract»

  • Deposits in a sealed-off CO2laser-type discharge

    In a sealed-off CO2laser, deposits are formed from the gas mixture. The removal of the gas in this way limits the lifetime of the laser. Fragments of these deposits are analyzed mass spectrometrically and their possible composition is given. After the discharge tube was pumped down, the gases released from the walls were analyzed. CO2was observed and it was apparently trapped... View full abstract»

    A 50-kV laser-triggered spark gap operated at repetition rates to 50 pps is described. Jitter of delay time as low as ± 0.1 ns was demonstrated. Dependence of delay and jitter was investigated as a function of gas mixture, pressure, laser power, and electrode material. Subnanosecond jitter was obtained with as little as 0.17 mJ in a 6-ns giant pulse from a Nd+3in a YAG laser. The d... View full abstract»

    This paper describes a new method of angle measurement by optical means that may prove useful in gyrocompass applications. In this device, the relative orientation of the spin axis of a transparent spherical rotor is determined by measuring the Fresnal drag effect associated with the motion. This is done by placing the spinning sphere in the path of the optical beam inside the cavity of a ring las... View full abstract»

    A periodic resonant reflector with thin air intervals is designed for a YAG:Nd3+laser in order to achieve emission of a line at 1.318 μ by suppressing the well-known line at 1.064 μ for reasons of laser safety. View full abstract»

    From an investigation of the fluorescence and laser tunability of 7-N-methylamino-4, 6-dimethylcoumarin, we have found a convenient means of extending the laser bandwidth and tunability by acidification of the solution. The general applicability of this method applied to other organic dyes is also discussed. View full abstract»

  • Theory of the two-photon absorption-fluorescence method of pulsewidth measurement

    A three-level model of a two-photon absorber is set up, and the response of the system to a pulsed excitation is calculated, including the effects of homogeneous and inhomogeneous broadening. The results are applied to the two-photon absorption-fluorescence (TPF) mesurement technique and it is shown that the larger of the two broadening mechanisms sets an upper limit to the spectral width of pulse...
