    Eleven fluorescing organic dyes were tested for their ability to alter the spectrum of a flashlamp in such a way as to increase the light intensity in one or more of the neodymium laser pump bands. A few of the dyes gave a marked improvement in the output energy of a pulsed Nd:YAG laser. Rhodamine 6G was identified as the best dye, giving better than 50 percent improvement in the laser output for ... View full abstract»

  • Propagation losses in metal-film-substrate optical waveguides

    The propagation losses in metal-film-substrate two-dimensional optical waveguides are calculated. Losses for confined modes may become large and are at least an order of magnitude larger for TM than for TE modes. Higher order modes suffer more loss than the fundamental mode. Such mode-dependent loss can make efficient mode analyzers, useful for integrated optics modulation schemes. View full abstract»

    This paper presents a theoretical treatment of the fluctuation mechanism involved in the generation of picosecond laser pulses with saturable absorbers. The processes responsible for the shortening of the pulsewidth and for selection of the most intense pulse are treated. Some experimental results that confirmed the treatment are presented. The influence of inertia of saturable absorber and nonlin... View full abstract»

    Intensity fluctuations of GaAs light-emitting diodes (LED) have been measured at 25°C ambient temperature in the frequency range of 25 Hz to 20 kHz. A dependence of optical fluctuations at low frequencies on diode current and also on the direction of emitted radiation has been found. View full abstract»

    An experimental study of the saturable absorption of SF6at high pressure with high incident laser flux is reported. Experiments with a high-pulse-power CO2laser show 15 orders of magnitude change in transmittance of SF6(17 torr pressure) at the P (16) CO2line and apparent saturation of the residual absorption at ...

    Spectral and other properties of a ruby laser pumped LiIO3pulsed doubly resonant parametric oscillator (DRO) are reported. This device is tunable from 1.12 to 1.83 μ with peak powers of 100 kW and 10-percent efficiency. The stability of the DRO is discussed. The output of the DRO was doubled into the 5600- 9150-Å range using a second LiIO3crystal. Peak second-harmon... View full abstract»

  • Theory of parametric oscillation phase matched in GaAs thin-film waveguides

    The operation of a parametric oscillator phase matched in a GaAs thin-film waveguide is considered. Parametric equations of motion for interacting waveguide fields at three frequencies are developed. From these equations we derive expressions for parametric gain and oscillation threshold. A specific orientation of GaAs allows optically smooth cleaved surfaces to form the oscillator cavity. Conditi... View full abstract»

    An interferometric technique was developed for detecting fast displacements of small areas in beam direction by less than \lambda /8 . It utilizes a modified Michelson interferometer and a He-Ne laser light source. The technique was applied to measure the temporal and spatial evolution of the thermal mirror deformation of a GaAs-Ga1-xAlx... View full abstract»

    The sensitivity of a broad-band dye laser to selective intracavity absorption is proportional to the number of oscillating modes. This result is obtained from a rate equation model, taking into account the spectral homogeneity, but spatial inhomogeneity of the laser saturation. An increase of absorption sensitivity by a factor of 105, compared to a single-pass measurement, is observed i... View full abstract»
