Title: Dynamics of traveling reaction pulses

Abstract

The growth of activator losses is accompanied by the decay of a traveling reaction pulse. In a ring reactor, this propagation threshold is present simultaneously with a threshold related to the ring diameter. The results of numerical experiments with pulses of an exothermal reaction reveal the transition from pulse propagation to a homogeneous hot regime, established regimes with periodic variations of the pulse velocity, and oscillatory decay of the pulse. When the medium becomes 'bistable' as a result of the variation in parameters, this factor does not prevent the propagation of pulses, but leads to changes in the pulse structure.

  • By transverse traveling-wave pumping the three dyes Rh6G, RhB and C311 with 700 psec pulses from a lambda = 337.1 nm nitrogen laser as pump light, we have obtained ASE pulses with durations of 45, 55, and 45 psec respectively.
  • We report amplification of picosecond pulses at high repetition rates in a 1.3 ..mu..m traveling-wave optical amplifier. At 4 GHz repetition rate, the small-signal chip gain is 20 dB, the amplified peak output power at the facet is 400 mW (corresponding to a pulse energy of 3 pJ/pulse), and there is no measurable pulse shape distortion of 12 ps pulses for gain compression up to 1.5 dB. We also directly measure the time constant of the gain recovery to be 100 ps.
  • Single-photon and two-photon traveling-wave excitation of superradiant emission in Rhodamine 6G by single-picosecond 1.06-$mu$ laser pulses is reported. In addition, results are presented on the application of optical Kerr-effect photography to a time-resolved spectroscopic study of the dye laser emission.
  • In the propagation of optical pulses through dispersive media, the frequency degree of freedom acts as an effective decohering environment on the polarization state of the pulse. Here we discuss the application of open-loop dynamical-decoupling techniques for suppressing such a polarization decoherence in one-way communication channels. We describe in detail the experimental proof of principle of the ''bang-bang'' protection technique recently applied to flying qubits in Damodarakurup et al. [Phys. Rev. Lett. 103, 040502 (2009)]. Bang-bang operations are implemented through appropriately oriented wave plates and dynamical decoupling is shown to be potentially useful to contrast a generic decoherence acting onmore » polarization qubits propagating in dispersive media like optical fibers.« less
  • A time-domain self consistent theory of a gyrotron traveling wave tube with a helically corrugated operating waveguide has been developed. Based on this model, the process of short pulse amplification was studied in regimes of grazing and intersection of the dispersion curves of the electromagnetic wave and the electron beam. In the first case, the possibility of amplification without pulse form distortion was demonstrated for the pulse spectrum width of the order of the gain bandwidth. In the second case, when the electrons' axial velocity was smaller than the wave's group velocity, it was shown that the slippage of themore » incident signal with respect to the electron beam provides feeding of the signal by “fresh” electrons without initial modulation. As a result, the amplitude of the output pulse can exceed the amplitude of its saturated value for the case of the grazing regime, and, for optimal parameters, the peak output power can be even larger than the kinetic power of the electron beam.« less
