    The dynamic Stark effect in optically pumped lasers is discussed. Javan's theory of three-level masers is extended and elucidated by transforming his expressions into new forms in which all of the major terms can be deduced from a modified energy-level diagram through simple physical arguments. The gain spectra of high-power 496-μm CH3F lasers are calculated from the theory. Contra... View full abstract»

  • Temperature and wavelength dependent properties of multiplate reflectors

    This paper describes a new approach to the design of multi-element resonant reflectors. These mirrors provide an effective means of controlling the spectral spread of high-gain laser oscillators, but the complexity of the reflectivity as a function of wavelengthR (lambda)has made the design of these systems rather difficult. However, we show that by making a two-dimensional plot of refl... View full abstract»

    This paper studies the dynamics of (dipole-dipole) laser induced collision processes. Coupled equations are numerically integrated, first over time, and then over impact parameter. Transition probability and collision cross section are given as a function of the detuning from theR = inftyfrequency of the separated atoms, and of the incident laser power density. Numerical results are com... View full abstract»

    A flowing HF transverse excitation (TE) discharge laser has been operated at 104pps for up to 109pulses. Preliminary testing at 100 pps produced 350-μJ/pulse output with reduced outputs at higher pulse rates. View full abstract»

    A new method for laser cavity dumping using an antiresonant ring laser cavity and an electrooptic phase modulator has been demonstrated on a CO2laser at 10.6 μm. Experimental results are summarized and the cavity and modulator design considerations for this type of cavity dumping are reviewed in this paper. Although the initial experiments were done at 10.6 μm, the antiresonan... View full abstract»

  • Dual frequency subnanosecond pulses from a millimeter-cavity dye laser

    Dual frequency dye laser pulses of subnanosecond duration can be achieved by taking advantage of the spiking behavior of two lasing dyes within a single high-loss cavity. Two 10-kW pulses 1.5 ns apart were observed, each of 600-ps width, at wavelengths of 565 and 615 nm, respectively. The phenomenon of spiking in organic dye lasers has received attention as a potential mechanism for the creation o... View full abstract»

    A simple model of photoionization of excited atoms by UV photons from capacitor spark discharges is suggested to explain the improvement in both plasma density production and laser efficiency noticed by several investigators when the proportion of helium in high-pressure CO2laser mixtures is increased. Such improvements with increased He proportion take place both with and without seedi... View full abstract»

    The performance of dye lasers with excited singlet-state absorption (ESA) at the pump and the lasing wavelengths is analyzed for short pulse pumped systems in the medium range of pumping intensities. Analytical and numerical solutions are presented for a wide range of the variable parameters such as ESA cross sections, the cavity reflectivity, and the pumping intensity. An experiment is described ... View full abstract»
