    Diode laser action has been obtained at 8.5μ with PbSe. This laser is of potential interest for terrestrial communications since its emission is in the 8-to-14-μ atmospheric window, a spectral region of high atmospheric transparency where attenuation due to scattering by haze is low. Fabrication techniques are described which are based on controlling carrier type and concentration by adj... View full abstract»

    The frequency separation between transverse modes of a ruby laser is measured using a Fabry-Perot interferometer and a high-speed camera. The results are compared with the theoretical predictions based on the curved-reflector theory. Satisfactory agreement is obtained. The measurements are verified by studying the output of the laser after application of transverse mode selection. The mode selecti... View full abstract»

  • Characteristics of mode-coupled lasers

    The effects of mode-coupling in a gas laser resulting from a time-varying loss within the optical cavity or from the non-linear characteristics of the inverted population are investigated both theoretically and experimentally. The dominant effect resulting from this mode-coupling is that the laser operates as a pulse regenerative oscillator which produces a periodic train of subnanosecond width pu... View full abstract»

    The development of coherent light sources has made possible new optical radar systems in which target information should be determined with a far greater accuracy than would be possible with a conventional microwave radar system. However, the same factors which make the improved resolution possible impose difficult requirements on the optical receiver. Presently available image detectors have very... View full abstract»

    Two types of photomultipliers exhibiting flat base-band response to ∼4 Gc/s are described. One photomultiplier employs crossed electric and magnetic fields, the other is purely electrostatic. At present both devices consist of eight Cu-Be secondary emission stages and an internally situated, opaque-backed S-1 photocathode. Current gain exceeds 105, and the transit time dispersion ...

    Narrow-band quantum counters with less than unit internal quantum efficiency are analyzed. The pump power dependent expressions for the transient and steady-state quantum efficiencies are derived. These quanties are discussed for "typical" trivalent and divalent rare-earth-doped insulator crystals, and the performance of two specific systems is presented. It is shown that to achieve high quantum e... View full abstract»

    The problem of energy exchange between two electro-magnetic modes of different frequencies and an acoustic mode is formulated and solved. The results of the quantum mechanical analysis are also analyzed in classical terms and are found to be consistent with the theory for parametric interactions. Specific cases treated include: parametric amplification of light, stimulated Brillouin scattering, an... View full abstract»

    This paper describes a model and provides the mathematical formulation for describing the spike pulsing phenomenon observed in optically pumped three-level lasers. The model is based on the pumping of electrons from a ground state to an excited pump band from which they relax very rapidly to the excited laser level. With population inversion then achieved, laser action starts and repetitive pulses... View full abstract»
