    The performances of two microwave sources used to produce fluorine atoms by dissociation of SF6for a CW hydrogen fluoride chemical laser are compared. The first device, large microwave plasma (LMP), is a slow-wave structure while, the other (surfatron) excites a plasma surface wave. Their performances, as far as electrical and chemical efficiencies are concerned, are quite similar when ... View full abstract»

    The Nd3+:YAG laser pumped by a CW 5-kW krypton arc-lamp was tuned to 19 different transitions from 1.052 to 1.444 μm by means of intracavity thin solid etalons and appropriately coated resonator mirrors. Each transition was tunable over 6-12 wavenumbers and most exhibited 10-30-W CW output, attaining 37 W at 1.319 μm and 52 W at 1.112 μm. The 1.061-μm line is 90 perc... View full abstract»

    Rate equations for anisotropic lasers were investigated theoretically. The effect of anisotropy of optical properties, such as emission cross section and resonant absorption loss, on the laser performance was examined quantitively. Conditions for dual-polarization oscillations (DPO), as well as formulas which relate the output power to the pump power and various other laser parameters, were given.... View full abstract»

    A convenient variation of Raman-induced Kerr effect spectroscopy (RIKES) which overcomes many of the previous limitations of coherent Raman spectroscopy is introduced. Quantum limited signal-to-noise ratios may be approached by the use of optical heterodyne detection (OHD). Detector current, linearly proportional and phase sensitive to the third-order nonlinear susceptibility, and linearly proport... View full abstract»

    Analytic expressions are derived to describe the ideal electrical behavior expected of a double heterostructure junction laser operating in the vicinity of its lasing threshold. The analysis is based on a laser model in which the current-voltage characteristic of the p-n junction is determined by recombination alone. The first, second, and third current derivatives of the junction voltage are comp... View full abstract»

    The emission frequency of an amplified spontaneous emission (ASE), optically pumped submillimeter (SMM) laser has been studied as a function of laser gas pressure for several different gases and SMM laser lines. For off resonant pumping, Fabry-Perot interfetometer scans indicate a shift in emission frequency between high- and low-pressure laser operation. In high-pressure operation, emission occur...

    Efficient operation of a high peak power and high-average power infrared dye laser, continuously tunable over the range of 10810-12160 Å, has been achieved by pumping with an Nd:YAG laser. A peak power as high as 4 MW with an average power of 390 MW was obtained. View full abstract»

    The scattering from dielectric-slab-optical waveguides having refractive-index inhomogeneities in the core region has been studied by solving the Maxwell equations together with the use of a stationary phase method. The scattering phenomenon is of interest since it provides the radiation pattern in the far-field region which is characterized by the statistical scale of inhomogeneities in a wavegui...

    Measurements of the small-signal gain of the laser medium produced by a combustion-driven CW chemical laser are presented. The laser characterized is a conventional supersonic flow chemical laser. A low-power CW chemical probe laser operating on a single line and single TEM00qmode was used for the measurements. Scans of the cavity in the streamwise direction were made by directing the p... View full abstract»

    The performance and spectroscopy was investigated for ultraviolet ion laser transitions in fluorine, chlorine, bromine, and sulfur. Three new transitions were found in bromine below 280 nm and 60-W peak power was observed for the strongest new line in Br IV? at 236.2465 nm. The wavelengths for the new and previously known transitions were measured to about 0.001 nm. Performance was optimized using... View full abstract»

    Transmission bandwidths of optical fibers would be maximized if their refractive index profiles were optimally graded. However, dispersive differences between fiber material constituents make the optimal power law profile exponent α depend on wavelength. This profile dispersion effect is significant for germanium borosilicate fibers and makes their observed transmission bandwidths change by m... View full abstract»

    We have built a low-power CW HF/DF chemical laser, designed to achieve high-frequency stability. Measurements are reported which characterize the instantaneous spectral width of the laser output to less than one part in 1011( \Delta \nu < 1 kHz) and the variations in absolute frequency of this emission with time to four parts in 1010( ...
