    An analysis of the interaction of ultrasonic waves with the junction-laser modes is performed, using first-order perturbation theory. It demonstrates that in the presence of sound waves, each laser mode is frequency-modulated with negligible harmonic distortion or mode mixing. It is also shown that bandwidths of several GHz, with high-modulation index are possible. View full abstract»

    The results of electron-beam experiments on undoped single-crystal CdS are presented. A description of the beam-injection apparatus is given. The relevance of various indications for lasing in this type of structure is discussed, and an operational definition of lasing threshold current is described. In this paper intensity versus pumping carves, stimulated-emission moding curves, and measurements... View full abstract»

    A parametric study has been undertaken to determine the gain characteristics of flowing CO2-N2-He lasers employing a transverse-discharge configuration. Unlike conventional cylindrical discharge tubes, in this device the gas-flow and electrical-discharge paths lie perpendicular to the optical axis. Box lasers with various aspect ratios and electrode configurations were evalua... View full abstract»

    Laser emission has been observed at 54 wavelengths between 11 and 41 μ in pulsed electrical discharges in BF3, BCl3, and BBr3. The emission wavelengths have been measured and the time behavior of the lines studied. Lasing in each of the gases produces total peak powers on the order of 10 to 100 mW. The addition of N2, He, or H2O to the di... View full abstract»

    A water vapor laser has been operated with a subsidiary grating Fabry-Perot resonator replacing one end mirror. Double-wavelength operation was obtained. Single-wavelength operation was obtained with strong rejection of shorter wavelength radiation, a variable effective reflectivity of the end mirror, and control of polarization characteristics of the cavity, allowing linear or circular polarizati...

    A method for stabilizing the frequency of a single- J - value CO2laser to the center of its output power versus frequency curve based upon the variation of the impedance of the plasma tube with the optical power extracted is described. Frequency modulation of the laser produces an ac component of voltage drop across the plasma tube, which is synchrono... View full abstract»

    The thermal and optical properties of CW Nd:YAlG laser rods have been measured before and during optical pumping with tungsten lamps. Instabilities in the optical properties during pumping were found to correlate reasonably well with the fluid flow characteristics of the coolant used. The importance of stable optical properties to the attainment of maximum laser radiance and amplitude stability is... View full abstract»

    It is shown how intracavity etalons can be optimally designed for axial mode selection and frequency stabilization of gas and crystal lasers. Relevant laser parameters, required etalon properties, and expected losses are determined. A simple frequency stabilization scheme based on birefringent etalons is described, which does not require laser modulation. Major problems associated with stable sing... View full abstract»

    The behavior of a He-Ne laser amplifier in the presence of an axial magnetic field has been studied experimentally by measuring Faraday rotation and gain for various values of input signal intensity. Two high-gain transitions in the 3.39-μ region were used for study-a J = 1 to J = 2 transition and a View full abstract»

    Three-wave parametric interactions are studied in media exhibiting group-velocity dispersion. Under certain conditions these interactions may be described by the same equations that govern pulse propagation in a two-level resonant system. This analogy suggests the existence of steady-state pulse solutions in the three-wave parametric system. Such solutions are found, and are analogues of pi and tw... View full abstract»
