    An AM mode-locked laser with a frequency doubler internal to the laser cavity is analyzed. Mathematical expressions are derived for laser pulsewidth, saturated gain, and second-harmonic output power. It is shown that the maximum second-harmonic power output available from the mode-locked laser is a factor of \sqrt {2} less than that available from an identica... View full abstract»

    We report "superradiant" near-IR dye laser emission, with peak of emission in the 690-930-nm range, from nitrogen-laser ( \lambda = 337 -nm)-pumped dye solutions including aluminum phthalocyanine chloride and seven polymethine cyanine dyes. View full abstract»

    Pulsed-laser action is described on a number of atomic transitions of ArI, one of which has not been reported previously. The addition of SF6to Ar shifts the laser action in the Ar from the ... View full abstract»

    In a previous letter we proposed a compression scheme which reduces the intensity of a laser pulse in an Nd:glass amplifier chain and thereby allows more efficient energy extraction. In this scheme the nonlinear index of refraction (n2) of the glass in the amplifier impresses a frequency sweep or "chirp" on the pulse. Further analysis is presented here. The stability to amplitude noise ... View full abstract»

  • Mode conversion in planar-dielectric separating waveguides

    The mode-conversion behavior of branching or separating planar-dielectric waveguides is studied theoretically as a function of branch asymmetry and taper slope. When the taper slope is large in a near-symmetric structure, considerable mode conversion will occur and the structure will act as a power divider. In an asymmetric structure with small taper slope, mode conversion is negligible and the st... View full abstract»

  • Bond-orbital model for second-order susceptibilities

    Publication Year: 1975, Page(s):40 - 45

    The bond-orbital model (BOM) for tetrahedral compounds is used self-consistently to calculate the second-order susceptibility. No adjustable parameters are used and agreement with experiment is good. The origin of the nonlinearity arises from a charge transfer as a result of the asymmetric polar energy between the anion and the cation. The model correctly predicts an optimum polarity to maximize s... View full abstract»

  • Pulse stretching and shape control by compound feedback in a Q-switched ruby laser

    Feedback control is employed to stabilize the output of a Q -switched ruby laser. A computational model of the rate equations plus feedback terms is used to examine pulse shapes with changing feedback parameters. It is shown that a lengthened flat-top pulse cannot be obtained with negative feedback alone, a compound feedback arrangement is suggested to facilitat... View full abstract»

    Using picopulses generated by a mode-locked ruby laser, we have measured the 3-8-Å bandwidth of a hole burned in the 0-0 transition of cryptocyanine in methanol and demonstrated the inhomogeneous chatacter of this transition. The population-rate equations are written for an inhomogeneous transition with two and four energy levels interacting with continuous or pulsed excitation. Using the num... View full abstract»

    The "Fluctuation Model" for the generation of ultrashort pulses by a saturable absorber has been discussed by a number of authors. This model has provided valuable insights into the mechanisms involved in passive mode locking; however, previous treatments have been incorrect in several important respects. These treatments have attempted to describe the behavior of the laser in terms of the evoluti... View full abstract»

    Radiation-pressure separation of molecules in a closed cylindrical geometry with radiation propagating along the axis has been analyzed. The degree of separation and separation efficiency are compared in the microwave, infrared, and visible-UV spectral regions for representative species. View full abstract»

    The recovery times for transient bleaching of the Q -switch dye bis(4-dimethylaminodithiobenzil)nickel (BDN) in the solvents dichlorethane and iodoethane have been determined. The lengths of pulses from an Nd:glass laser mode locked with BDN have also been measured by means of the two-photon fluorescence technique. View full abstract»
