    Diagnostic techniques are reviewed in the context of insights they provide to physical processes dominating the implosion of laser fusion targets. Specific examples chosen from recent experiments demonstrate that adequate diagnostic techniques, resolved to microns and picoseconds, have been developed for the demanding requirements of laser driven "exploding pusher" targets. Future diagnostic needs... View full abstract»

    Periodic corrugated waveguides with wave confinement in both transverse dimensions are analyzed. The description includes the cases of grating misalignment (tilt) and curvature; for a tilt angle θ, the resonant wavelengths vary as(cos theta)^{-1}. Coefficients for intramode coupling (identical contradirectional modes) and hybrid (intermode) coupling are calculated as functions of &... View full abstract»

    26 new FIR laser lines have been observed in CO2laser pumped CH3OH, and together with some previously observed lines their wavelengths have been measured with a relative accuracy of3 times 10^{-4}by using the FIR resonator as a scanning Fabry-Perot interferometer. Based on the internal consistency of the data, it is suggested that a number of the lines originate fr... View full abstract»

    A rate analysis approach is used to evaluate an example of the recently observed optogalvanic effect in discharge plasmas. The coupling of level populations through radiative transitions and electron collisions is solved in a modified Schottky approximation for a glow discharge. The effects of radiation trapping, superelastic collisions, and buffer-gas pressures are treated in the analysis. The ut... View full abstract»

    Single-mode CW oscillations at absorption lines of neon from the1sstates to the2pstates were achieved by inserting a Faraday filter in an argon-laser-pumped dye laser cavity without any other wavelength selective elements. The oscillations at absorption lines were selected by choosing adequate values of the filling pressure of a neon discharge tube and a magnetic field streng... View full abstract»

    A mode-locked Nd:YAG laser capable of generating pulses substantially shorter than the present limit of 30-50 ps, while retaining the stability of active mode locking, would be a useful development. We present here a simplified theoretical analysis and a preliminary experimental verification of the use of an optical Kerr cell as a passive lossless pulse compressor inside aQ-switched and...

    Rate equations for multitransition lasers were investigated theoretically and the effect of fluorescence properties of multilevel lasers on laser performance was examined. Simultaneous oscillations of different transitions (MTO) were found to occur due to the difference in resonator loss for individual transitions. Conditions for single transition laser oscillations (STO) as well as oscillation st... View full abstract»

    A theoretical model has been developed to examine the behavior of UV preionized, fast transverse discharge, rare-gas halide lasers. The model integrates the time dependent circuit equations for the discharge, the kinetic equations for the important atomic and molecular species and electrons, and the equations describing the growth of the spontaneous and stimulated emission. Results of KrF and ArF ... View full abstract»

    The operation of crossed-beam gratings is analyzed in terms of diffraction efficiency and beam quality, following Solymar's method's General solutions for arbitrary beam widths, general beam profiles, and illumination with two beams are derived. A scheme for improving the beam quality of these gratings is proposed. The analysis should be useful in integrated optics for designing beam expanders, be... View full abstract»

    Optical waveguides have been fabricated from silver nitrate melts diluted with sodium nitrate. Several important advantages are gained, including control over the surface refractive index value. On the basis of regular solution theory, the relationship between the surface index and the melt dilution is determined. Modification of the index profile with dilution, as predicted by interdiffusion theo... View full abstract»

    Experimentation with a pulsed, angle-tuned LiNbO3optical parametric oscillator revealed the dependence of pump power depletion and conversion efficiency on pump laser beam divergence. Mathematical expressions, developed for these parameters, were based on a spherical-wave model. Calculated results and comparison with experimental observations indicate the degree to which phasefront curv... View full abstract»

    The detection of a fluctuating signal in the presence of noise is considered for a doubly stochastic Poisson counting system that is subject to fixed nonparalyzable detector deadtime. Explicit expressions are obtained for the likelihood-ratio detection of a modulated source of arbitrary statistics in the presence of Poisson noise counts. Receiver operating characteristics (ROC curves) are presente... View full abstract»

    We have explored the operating characteristics of UV preionized discharge lasers producing 10-100 mJ from noble-gas/ monofluoride excimers. We have studied in detail the temporal characteristics of the discharge, the effects of instabilities, variations of circuit parameters, and the effects of varying degrees of preionization on energy deposition and lasing. Spectral characteristics, tuning, stab... View full abstract»

    Single- and double-pulse experiments have been conducted on a moderately large bore (19 mm) Sr+ cyclic ion laser oscillating at 1033 and 1092 nm. The dependence of the output energy on the bore temperature, buffer gas (HE) pressure, discharge capacitance, discharge voltage, and timing between successive pulses was determined. Saturation in the output energy as both the capacitance and voltage are ... View full abstract»
