    The experimental results of our studies of metal evaporation under powerful optical radiation are presented. The theory of this phenomenon based on a liquid-vapor phase transition is developed. An approximate solution of the Clapeyron-Clausius equation is applied to the present problem. The method permits calculations of metal surface temperature versus incident light intensity I0. When...

    Demonstrations of diffraction-limited performance from a CW diffusion-type HF chemical laser are reported. A novel type of edge-coupled nonconfocal unstable resonator consisting of a convex mirror and a diffraction grating is used. A new technique of coupling power out of an unstable resonator different from the edge coupling previously suggested by Siegman is also applied. This consists of coupli... View full abstract»

    The performance characteristics of a continuously pumped doubly resonant optical parametric oscillator have been studied in detail. Using barium sodium niobate as the nonlinear material threshold for oscillation, as low as 3 mW has been observed. At higher pump power levels an efficiency exceeding 50 percent and a tunable output power of nearly 80 mW (signal plus idler), have been achieved. The ef... View full abstract»

    The vibration-vibration energy transfer of CO2gas initially excited to the first asymmetric stretch level (0001) has been observed. Collisional pumping to the (0111) combination level is measured by monitoring the fluorescence due to the (0111) → (0110) band. The rate constant for the process: CO2(0111) + CO2 View full abstract»

  • Characteristics of metal-insulator-metal point-contact diodes used for two-laser mixing and direct frequency measurements

    The frequency response characteristics of metal-insulator-metal (MIM) diodes used for direct-frequency measurements in the submillimeter and infrared spectral region have been determined and it is found that these may be described by a simple model based on aerial impedance and barrier shunt capacitance. In addition, an MIM diode has been used to detect visible radiation from an argon ion laser. View full abstract»

    Zero-power gain measurements in a supersonic diffusion-type CW HF laser have been made using a pulsed HF probe laser. A peak zero-power gain of 10 percent/cm was measured on aP_{2}(3)vibrational-rotational transition and 7 percent/cm on aP_{1}(6)transition for flow rates corresponding to 1.8 kW of closed-cavity power. The variation of zero-power gain with rotational quantum n... View full abstract»

  • Selection mechanisms of transverse modes in semiconductor injection lasers

    A discussion of the transverse mode selection in the conventional double-heterostructure injection lasers is given. The mechanisms considered as responsible for mode selection are 1) the nonnormal incidence in the plane perpendicular to the junction of the EM waves at the end faces; and 2) an uneven gain distribution across the active region. By using a multilayer waveguide model, results are pres... View full abstract»

    Effects of substitution by auxochromic groups on the electronic spectra of aromatic compounds are discussed. Depending on the location and direction of the singlet-singlet (S-S) relative to the triplet-triplet (T-T) oscillators within the molecular frame, substitution by an auxochromic group may cause T-T absorption bands to move into or out of the fluorescence region, or they may be left unchange...

    In many uses of lasers, the minimization or elimination of power reentering the laser is necessary to ensure its stability. It is pointed out here that the frequency-shifting properties of an acoustooptic light deflector can be used for this purpose. By using the deflected beam from a Bragg deflector, stability of the laser is obtained when the frequency of the acoustic wave is chosen such that th... View full abstract»

    The application of the Wallis and Pomerantz electrostatic sealing technique to low-temperature glass-to-glass vacuum tight optical window seals is discussed. The successful sealing of vacuum tight quartz optical windows to quartz tubing at the Brewster angle is described and problem areas are defined. A brief discussion of the sealing mechanism is given and the general equations are defined. View full abstract»
