    Direct measurements of optical gain using a probe laser beam for the laser dye cresyl violet perchlorate (CVP) in methanol solution using longitudinal pumping at two different wavelengths are described. An analysis of these longitudinal pumping experiments is developed and analytical expressions relating measured gain to the measured pump laser transmission are presented. This analysis is develope... View full abstract»

    The method of conformal transformations is applied to the analysis of waveguide bends. Equivalent structures are obtained that permit solution by traditional methods of optical waveguide analysis. Losses associated with both curvature and with the transition from straight to curved guides are discussed and simple first-order expressions that describe the dependence of the losses on waveguide param...

    The results of measurements on a GaAs-double-heterostructure (DHS) laser used as an optical amplifier are reported. The laser's amplifying guide is coupled to an optical fiber with a rectangular core. The laser amplifier can be operated either in the traveling-wave or the resonator mode. The gain, noise, and performance of the amplifier when driven hard into saturation were measured as a function ... View full abstract»

    We report a comprehensive study of the operation of a laser using the organic scintillator dye POPOP in the vapor phase. Laser operating parameters have been determined, and we describe tuning experiments which demonstrate an oscillation range of 25 nm. Gain measurements as a function of wavelength and time are reported for transverse pumping with the 337.1-nm output of a pulsed N2laser... View full abstract»

    Oppositely directed running waves in a ring laser saturate themselves and one another by population depletion. In addition, as the Doppler broadening decreases, they saturate one another by scattering off induced Bragg gratings in the medium, i.e., off spatial holes burned into the population difference. This increased coupling results in bistable operation near the atomic line center for Doppler-... View full abstract»
