“…Multiple scattering process of particles was at the center of attention in many investigations (see for example [1][2][3][4][5][6]). The classical aspects of multiple scattering lights are in the potential applications in holography, medical instrumentation, laser spectroscopy [6][7][8], LIDAR [9,10], and nonlinear optical mixers [11][12][13][14][15]. Recently, the specific attention is given to the new type of coherent emissions, which occur not only among the same quanta but between the photon groups generated in the nonlinear interaction of the electromagnetic field (EMF) with emitters (atoms, molecules, biomolecules, etc).…”

The description model of the multiple scattering lasers using the superposition states between the generated photons in the ensemble of bi-modes of the resonator field, we introduced a concept of indistinguishable energy portions generated in the resonator following multiple scattering. Each of these quasi-quanta has energy equal to the difference between the pumping and scattering quantum energies at each step of multiple scattering. The conversion of the photons in the external electromagnetic mode of the resonator destroys this cooperative correlation between the bi-modes and established conservation lows during the cooperative emission. The master equation containing two parameters connected with the gain of quasi-energy portions, and their annihilation due to the losses from the resonator, is proposed. The competition between these two processes is numerically studied. An attractive problem is connected with established quantum correlations between the photons belonging to non-adjacent modes of the cavity. The time behavior of the evolution of correlations between such modes is observed. This conception may be used for the teleportation of information in other modes during the multiple Raman conversion.

“…For example, in the single step Raman scattering, L = l/2, and into two steps of multiple scattering processes L = (l/2) × 2. To find the connection between the l and the number of pump photons n 0 , below we represent the solution of Schröinger equation (17) in another form than it was described in Exp. (18).…”

The cooperative models of the bimodal field in the multiple quantum scattering nutations are discussed and proposed for possible detections in open cavities. We proposed two types of cooperation between the converted photon processes in these multiple steps of scattering nutation in the cavity. One of them takes into consideration the cooperative process between the photons of each step of the multiple steps of Raman conversion. The second cooperative process takes place between the photons belonging to different steps of multiple scattering conversions. The proposed novel bimodal entangled sources take into consideration both the coherence and collective phenomena between the photons belonging to the system of the bimodal field obtained in multiple scattering emissions. The application of higher-order multiple Raman bimodal coherent field in quantum information is proposed.

An Eml31oyee-Owned Company DISTRIBUTION OF THIS DOC'JMEN[ iS LJNLiMITED, REPORTS Although FASAC examines world applied science, emphasis is placed on research in the Soviet Union. The Center reports on what the Soviets call exploratory research (akin to Department of Defense 6.1 and 6.2 research), which seeks to translate developments in fundamental research into new technology. Further, as the globalization of advanced technology proceeds, more FASAC assessments are of foreign (non-Soviet) research efforts. The Center generally does not report on technology already being incorporated in engineering applications. Inaddition to an assessment of the quality and emphasis of foreign research, a Center report provides milestones for monitoring subsequent progress, lt also provides elements of a net technical assessment of the balance with US science, without being an out-and-out comparison. ORGANIZATION The permanent Center staff includes the Center's Director, two Senior Scientists, a Senior Editor, a Technical InformationSpecialist, and an Assistant Editor. FASAC panels consist of expert consultants from academia, industry,and government,typicallysixto eight members per panel. Each panel assesses the status and potential impacts of foreign applied science in a selected area. Panel members are selected by the followingcriteria: leading authority in the field; recent "hands-on" experience; knowledgeof foreign research; and knowledge of the directionof US research programs. The panels review broadareasof applied scienceandthen focuson particularactivitiesof interestto their assessment. At intervals, panelsare convenedto reassesspastFASAC topicsinvolvingareas of rapidlyadvancingscienceandtechnology of particularimportance.
