Adiabatic following model for two-photon transitions: Nonlinear mixing and pulse propagation
(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 ...
Biological properties of a canine distemper virus isolate associated with demyelinating encephalomyelitis
(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 ...
Adiabatic following and slow optical pulse propagation in rubidium vapor
(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 ...
Self-focusing of light by potassium vapor
(American Physical Society, 1970-04-20)
Raman-shifted ruby-laser light on the high-frequency side of the 2P3/2 resonance line (7665 A) of potassium was self-focused by a dilute potassium gas.
Comment on the relationship between an exact two-photon solution and a two-photon vector model
(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 ...
Behavior of electron-spin echoes and photon echoes in high fields
(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 ...
Characterization of Pseudomonas aeruginosa mutants deficient in the establishment of lysogeny
(American Society for Microbiology, 1978-06)
Mutants of Pseudomonas aeruginosa with impaired ability to establish a lysogenic relationship with temperate bacteriophage (Les-) have been isolated. These les mutations map to two areas of the P. aeruginosa chromosomal ...
PaeExo IX: A unique deoxyribonuclease from Pseudomonas aeruginosa active in the presence of EDTA
(Oxford University Press, 1979)
A new deoxyribonuclease, PaeExo IX, has been purified to electrophoretic homogeneity from extracts of Pseudomonas aeruginosa strain PAO. This enzyme, which is active in the presence of EDTA, is equally efficient in hydrolyzing ...
Optical pulse compression
(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 ...
Coherent excitation, incoherent excitation, and adiabatic states
(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 ...
