    The relaxation of low-lying excited states of Tm3+ions doped in YAG, YAlO3, and Y2O3due to photon and phonon emission is studied theoretically. Stimulated emission cross sections (integrated over frequency), fluorescence lifetimes, and radiative quantum efficiencies are calculated and their implications for laser operation on the 2.3-μm3F...

    Transversely pumped dye-laser systems are investigated theoretically and experimentally. A set of coupled rate equations for the excited-state population densities and for the photon fluxes in both directions, at all wavelengths, is presented. Both the temporal and spatial dependence of these quantities are accounted for. The equations are solved numerically for a variety of practical situations, ... View full abstract»

    A simple CuI double-pulsed laser was built. The dependence of power output on the delay between the two excitation pulses, temperature, and the type of buffer gas has been investigated. The laser pulse duration was measured. View full abstract»

    We compute coupling coefficients for TE modes as a function of tooth height, active layer thickness, and Bragg scattering order in single-heterostructure (SH) and double-hetetostructute (DH) distributed feedback (DFB) diode lasers for a variety of corrugation shapes. In particular, equations for rectangular, sinusoidal, and triangular shapes are evaluated; the last both in the symmetric and saw-to... View full abstract»

  • Rotational-vibrational line competition in a dual-polarization CO2laser

    A dual-polarization CO2laser can be caused to operate such that the two polarization modes correspond, respectively, to different rotational-vibrational lines. Interline competition effects, similar to those described previously, here also result in a mode power change with optical frequency which can be utilized as a convenient and sensitive optical frequency discriminant.

  • Fuels for a premixed pulsed HCl laser

    HCl pulsed chemical lasing was obtained from several premixed R-Cl/HI mixtures when initiated by a transverse pulsed discharge. The relative merits of these mixtures were compared to a premixed H2/Cl2mixture. For a constant stored electrical energy several mixtures have been found which give higher specific power than the H2/Cl2system. In addition, it ha... View full abstract»

    A newly developed systematic procedure to calculate the real and imaginary parts of the change in propagation constant of a surface-wave mode on a curved open waveguide of general cross section is used here to determine these quantifies for the TE modes of an asymmetric slab waveguide and for all the modes of an optical fiber. Comparison of these results with the existing literature points up the ... View full abstract»

    The 3371-Å nitrogen laser power produced by a relativistic electron beam propagating into nitrogen gas is calculated. The excitation contribution of cascade electrons is found to be negligible, compared to the excitation caused by plasma electrons drifting in the inductive electric field produced by the beam. The extensive experimental data on nitrogen are used wherever possible in the calcul... View full abstract»

  • Frequency-domain analysis of the mode-locked and frequency-doubled homogeneous laser

    Publication Year: 1975, Page(s):857 - 862

    A frequency-domain analysis of the mode-locked intracavity frequency-doubled laser is pursued. An expression for pulse-width is derived based upon basic laser parameters and the nonlinear coupling of the frequency doubler. It is found that mode locking induces an additional loss to the cavity even in the ideal case, so that the frequency-doubled output power at optimum coupling is less than an opt...

  • Self-focusing phenomena in air-glass laser structures

    The effect of the air space on self-focusing instability growth rates has been considered for glass laser systems. The situation may be viewed as a min-max problem in which the air space may be adjusted to minimize the fastest growing instability. A solution exists to the min-max problem which reduces the problem to the solution of a single transcendental equation. Solutions to this equation indic... View full abstract»
