    We analyze second-harmonic generation (SHG) with focused pump beams in the high-conversion regime where pump depletion is significant. Numerical solutions of the coupled equations for pump and harmonic fields are obtained for the cylindrically symmetric case of collinear phase matching. The optimum values of phase mismatch and confocal parameters σ and b... View full abstract»

  • Simple hydrodynamic model accounting for intermediate stages of temporal development of laser-induced plasmas

    Publication Year: 1970, Page(s):770 - 775

    A theoretical model is presented that satisfactorily describes intermediate stages of the propagation of laser-induced plasmas created by focusing laser light on air and other materials. Two stages can be distinguished during the intermediate phase of the plasma expansion. The first is an approximately linear stage, of high speed, governed by the group speed of X View full abstract»

  • Cross-correlation detection of subnanosecond optical pulses

    A scheme for the direct display on a low-frequency oscilloscope of periodic subnanosecond optical pulses from mode-locked lasers is described. Low-power pulses can be displayed since no optical elements nonlinear to the power are used. Initial results with mode-locked He-Ne lasers are given. View full abstract»

  • Response of a CW Nd3+:YAG laser to sinusoidal cavity perturbations

    Sinusoidal perturbations are applied to the resonator of a CW Nd3+:YAG laser to study the response of the system. Two kinds of resonances are observed. The resonant AM mode exhibits a sinusoidal modulation in the output and its frequency is determined by the pumping power and cavity losses. The spiking mode shows a train of regular pulses and its frequency is constant. Nonlinear coupled... View full abstract»

  • Efficient octave-bandwidth microwave light modulators

    The use of wide-bandwidth interdigital microwave circuits to provide electrooptic modulation of light is discussed. Two models employing lithium niobate crystals of different aspect ratios have been constructed and tested. Both have nominal bandwidth from 1.0 to 2.0 GHz but actually give somewhat greater modulation bandwidth. Single-pass modulation tests made using 6328-Å light at RF drive po... View full abstract»

  • Multiphoton ionization of rare gases at 1.06µ and 0.53µ

    The interaction between an intense focused beam of optical photons and matter in gaseous form at low pressure (10-3torr) brings into play some strongly nonlinear processes. These multiphoton processes occur through the simultaneous absoprtion of several quanta by an atom that may be thus either excited or ionized. The orders of nonlinearity of the interaction of a multimode ... View full abstract»

  • Modulator frequency detuning effects in the FM mode-locked laser

    The mode-locking behavior of a homogeneous laser with an intracavity FM modulator changes rapidly and asymmetrically when the modulation frequency is detuned by small amounts from its optimum value. We develop here a simple analysis of these detuning effects. The analysis gives explicit expressions for all aspects of the mode-locking behavior as functions of detuning. A physical interpretation of ... View full abstract»

  • Spectral coincidences between emission lines of the CO laser and absorption lines of nitrogen oxides

    Several spectral coincidences between carbon-monoxide laser emission lines and absorption lines of NO and N2O4have been observed, and absorption measurements have been taken. These data are presented and discussed along with similar spectral coincidence observations made previously using the helium-neon and iodine lasers. Other coincidences between CO-laser lines and NO... View full abstract»

  • Improvement of optical parametric oscillators by nonresonant pump reflection

    Several important characteristics of optical parametric oscillators can be substantially improved by nonresonantly reflecting the pump wave back upon itself after it has passed through the nonlinear medium. Benefits are reduced thresholds, decreased buildup times, and improved efficiencies. Steady-state analyses of doubly and singly resonant oscillators are presented. View full abstract»
