      Grischkowsky, D.; Hartmann, S. R. (American Physical Society, 1970-07-01)
      The amplitude of the electron-spin or photon echo from an ensemble of isolated atoms (echo atoms) interacting with magnetic-nuclear neighbors is calculated as a function of the magnitude and the orientation of an applied ...

      Grischkowsky, D.; Armstrong, J. A. (American Physical Society, 1972-10)
      The narrow-line output of a dye laser on the low-frequency side of the 2P1/2 resonance line (7948 A) of rubidium was self-defocused by passage through dilute rubidium vapor. The defocusing was caused by the electronic ...

    • Adiabatic following and slow optical pulse propagation in rubidium vapor 

      Grischkowsky, D. (American Physical Society, 1973-06)
      Short pulses of narrow-line low-intensity dye-laser light nearly resonant with the Zeeman-split 2P1/2 esonance line (7948 A) of rubidium were observed to propagate through dilute rubidium vapor as slowly as (1/14)c. These ...

    • Observation of self-steepening of optical pulses with possible shock formation 

      Grischkowsky, D.; Courtens, Eric; Armstrong, J. A. (American Physical Society, 1973-08-13)
      Near-resonant light pulses were steepened by passage through Rb vapor. The rise time changed from typically 4 nsec to less than 1 nsec, and complicated envelopes developed. The self-steepening, well described by adiabatic ...

    • Optical pulse compression 

      Grischkowsky, D. (AIP Publishing, 1974-11-15)
      Dramatic and controllable reshaping of frequency-modulated dye laser pulses has been observed. The pulses, nearly resonant with the 2P1/2 line (7948 A) of Rb, first passed through a LiNbO3 frequency modulator, and then ...

    • Theory of the dispersive modulator 

      Grischkowsky, D.; Loy, M. M. T. (AIP Publishing, 1975-02-15)
      The recent observations by Loy of amplitude modulation and compression of infrared laser pulses caused by passage through the dispersive modulator (a cell containing dilute NH3 vapor with a Stark-modulated resonant frequency) ...

    • Biological properties of a canine distemper virus isolate associated with demyelinating encephalomyelitis 

      Confer, Anthony W.; Kahn, Donald E.; Koestner, Adalbert; Krakowka, Steven (American Society for Microbiology, 1975-04)
      A canine distemper virus (CDV), designated R252, originally recovered from a dog with demyelinating encephalomyelitis was shown to reproduce this disease in gnotobiotic dogs with a high incidence as compared to other CDV ...

    • Self-induced adiabatic rapid passage 

      Grischkowsky, D.; Loy, M. M. T. (American Physical Society, 1975-09)
      We show that, by virtue of the linewidth reduction provided by counter-propagating beams, it is possible to use the optical Stark shift to sweep a two-photon resonance through the sum frequency of the applied light while ...

    • Triethyl-n-hexylammonium triethyl-n-hexylboride: A new antimicrobial showing activity against Candida albicans and gram-positive bacteria 

      Rosenthal, K. S.; Storm, D. R.; Ford, W. T. (American Society for Microbiology, 1975-10)
      The organic salt triethyl-n-hexylammonium triethyl-n-hexylboride (N2226 B2226) has biostatic effects against two gram-positive bacteria, Bacillus subtilis and Micrococcus luteus, and the yeast Candida albicans. Escherichia ...

    • Adiabatic following model for two-photon transitions: Nonlinear mixing and pulse propagation 

      Grischkowsky, D.; Loy, M. M. T.; Liao, P. F. (American Physical Society, 1975-12)
      Two-photon resonantly enhanced parametric generation processes have generally been described using time-dependent perturbation theory. In this paper we show that a theory of two-photon coherent effects can be used to derive ...

    • Purification and properties of two deoxyribonucleases of Pseudomonas aeruginosa 

      Miller, Robert V.; Clark, Alvin J. (American Society for Microbiology, 1976-08)
      A survey of the major deoxyribonucleases in Pseudomonas aeruginosa strain PAO was undertaken. Two activities predominated in Brij-58 lysates of this organism. These have been purified from contaminating nuclease activities, ...

    • Coherent excitation, incoherent excitation, and adiabatic states 

      Grischkowsky, D. (American Physical Society, 1976-08)
      Coherent excitation of an atomic excited state occurs during the propagation of near-resonant light pulses and is responsible for the induced polarization. Simultaneously, incoherent excitation occurs due to the relaxation ...

    • Comment on the relationship between an exact two-photon solution and a two-photon vector model 

      Grischkowsky, D.; Brewer, Richard G. (American Physical Society, 1977-04)
      The exact pulse solution of Brewer and Hahn for optical two-photon transitions is shown to reduce in the adiabatic limit to the two-photon vector model used by Grischkowsky, Loy, and Liao. The connection between the two ...

    • Prophage F116: Evidence for extrachromosomal location in Pseudomonas aeruginosa strain PAO 

      Miller, Robert V.; Pemberton, J. M.; Clark, Alvin J. (American Society for Microbiology, 1977-06)
      F116 is a temperate-generalized transducing phage of Pseudomonas aeruginosa. Genetic evidence leads to the conclusion that F116 prophage DNA is maintained extrachromosomally as a plasmid. Preliminary physical evidence is ...
