    The detection of low-level optical frequency radiation, such as that encountered in laser communication systems, is often accomplished with a photomultiplier tube. The photomultiplication process, however, is itself a random process. In this paper a formula for the statistics of the number of electrons after k stages is derived in the form of a recurrence rela... View full abstract»

    Properties of tungsten-nickel point contact diodes, when used as harmonic-generator mixers, were measured. The measured properties are those which will be useful to workers wishing to use these high-speed devices (faster than 10-14s). Some of the properties measured were : the decrease in signal with mixing order; the detected signal as a function of laser frequency; and the power requi... View full abstract»

    Neodynium doped calcium lanthanum silicate oxyapatite (Nd:CaLaSOAP) has properties intermediate between Nd:YAG and Nd:glass that make it desirable for use as a pulsed-mode-locked oscillator at 1.06 μ. Time resolve spectroscopy, high speed image converter streak recordings, and two-photon fluorescence pulse duration measurements were used to investigate the output of such a laser. Pulse durati...

    The high efficient generation of the second harmonic of ruby laser in rubidium dihydrogen arsenate (RDA) is reported. A peak harmonic power of 52 MW was obtained with a fundamental power of 110 MW. In addition, the temperature variation of the birefringence has been measured to be d(n_{2}^{e} - n_{1}^{o})/dT = (9.3 \pm 0.4) \times 10^{-6}\deg C^{-1} . View full abstract»

    Solutions of the wave equation are obtained for planar guides whose dielectric constant ε is anisotropic and decreases exponentially in the direction perpendicular to that of wave propagation. Although for TE modes the solutions are quite similar to those obtained earlier for exponentially varying but isotropic ε, there are some singificant differences for TM modes. The condition for sin... View full abstract»

    A rate equation analysis of convective CO electric-discharge lasers (EDL's) is presented. The spatial distribution of CO vibrational levels is governed by a kinetic master equation which contains terms representing electron impact pumping, vibration-vibration (VV) and vibration-translation (VT) energy transfer, and spontaneous and stimulated emission. Electronic pumping rates are derived from the ... View full abstract»

    Efficient second-harmonic generation at 5321 Å has been achieved in CDA and CD*A. At 50-MW pump power, loss-free peak power-conversion efficiency of 57 percent and 45 percent were obtained in CDA and CD*A, respectively, The nonlinear optical constant, corrected for multimode fluctuations, was found to be d_{36}(CDA) = d_{36}(CD*A) = (0.96 \pm 0.11) \times ...

    Single-mode rate equations are solved in the small-signal limit to determine the oscillation frequency and decay constant for relaxation oscillations in an intracavity frequency-doubled Nd:YAG laser. It is found that improved stability is noted for nonlinear coupling constants greater than 10-5. Eventually, cavity perturbations become critically damped with increased coupling, and oscil...

    This paper investigates the diffraction of light by apodized apertures. The diffraction equation is solved numerically starting with an apertured plane wave or Gaussian beam. A function chosen to characterize spatial intensity modulation is then plotted versus Fresnel number for differing amounts of apodization so that the benefit gained thereby may be quantitatively assessed. In addition, the ene... View full abstract»
