  • Astigmatic Gaussian beams produced by axially asymmetric laser cavities

    Gaussian beams generated within astigmatic resonators are themselves astigmatic, having wavefront curvatures and spot sizes that are different when measured in two orthogonal directions. Expressions are derived for the confocal parameters, spot sizes, waist positions, and stability conditions of beams formed within spherical mirror resonators that contain one or more inclined plates (or Brewster-e...

  • Double resonance in gaseous lasers - Linewidth dependence

    Publication Year: 1969, Page(s): 521

    The dependence of the saturation parameter of a double-resonance laser upon atomic linewidths for small RF perturbations was deduced incorrectly from general equations given in [1]. The correct expression for the saturation parameter is derived. Experimental observations are in agreement with the theory. View full abstract»

  • Simple technique for the detection of oscillation at 3.39 µ in a He-Ne laser operating at 632.8 nm

    Publication Year: 1969, Page(s):524 - 526

    A simple technique is reported for determining if oscillation is occurring simultaneously at 3.39 μ and 632.8 nm in a He-Ne laser. It relies on observation of modulation of the output power at 632.8 nm when a variable path length element is introduced into the optical cavity of the laser. The technique is applicable to other gas laser systems where competition for upper level populations occu... View full abstract»

  • Short time-constant thermal self-defocusing of laser beams

    Time constants as low as 20 μs have been observed when the beam of a helium-neon laser is focused on a small spot on a thin dye sample and the thermal self-defocusing effects observed. The short time constant arises mainly from the small spot size, but to some extent from axial heat flow to the cell ends. The analysis takes into account the axial heat flow, the variation of spot size within t... View full abstract»

    Experimental results of electrooptic deflection at 1 GHz using KD*P prisms are presented. Using iterated KD*P prisms of 1 cm active length in a parallel plate resonator, deflections up to 3.9 mrad were obtained at -10°C. This deflection corresponds to 8 resolvable spots. View full abstract»

  • Spectrum and width of mode-locked laser pulses

    Cited by:  Papers (9)

    An analytical theory is given of the spectrum of the pulses generated by a ring laser that is mode locked by a synchronously modulated absorber. A steady-state solution is defined by requiring that, in a round trip, the joint effect of the active medium and the modulated absorber leave the pulses unchanged. The resulting integral equation is solved approximately, and the frequency spectrum of the ... View full abstract»

    Giant pulse lasers with slowly opened Q switches have experimentally been demonstrated to have a significantly lower beam divergence than the same laser with a quickly opened Q switch. The two types of slowly opening Q switch in most common use are rotating prisms and Faraday rotators. In th... View full abstract»

  • Theory of laser self-locking in the presence of host dispersion

    A theory is developed of laser mode locking due to saturable absorbers when the dispersive property of the active material is taken into account. The electric field within the cavity is expanded in terms of cavity modes, the problem is treated under the rate-equation approximation, and only third-order nonlinear polarization terms of the dye are considered. The field is assumed to be made of View full abstract»

  • Saturation of infrared absorption in gaseous molecular systems

    Saturable absorbers for use in the infrared, consisting of molecular gases, are considered. A basic objective of the study is the understanding and prediction of saturation behavior. A model for the absorber is developed. Features considered include 1) strong interaction between the absorbing pair of vibrational-rotational levels and numerous neighboring levels; 2) spatial diffusion of molecules; ...
