10th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM 2010). 2nd IEEE International Workshop on THz Radiation: Basic Research and Applications (TERA 2010)
The process of photon emission, that accompany photon pair production in strong magnetic field has been studied in nonresonant case. Angle dependence and dependence on final photon polarization are analyzed for this process. Total probability for the nonresonant process of photon emission 106 s-1 is three order of magnitude less, than resonant one.
Modeling of the random lasing in diffusive regime by Monte-Carlo method and Kubelka-Munk theory has been carried out. It has been obtained the experiment-corresponded dependencies of radiation parameters on media characteristics. The optimal samples parameters for effective lasing have been found.
The nonresonant scattering of a photon by an electron (Compton scattering) in the field of a pulsed light wave is investigated theoretically. The approximation when a pulsewidth is considerably greater than the characteristic time of the wave oscillation is considered. The analytical expressions for the amplitude and cross-section of mentioned process are derived. It is concluded, that the total cross-section...
The process of resonant scattering of a lepton by a lepton in the field of pulsed light wave in general relativistic case is studied theoretically. It is demonstrated, that the obtained resonant differential cross-section of the scattering of an electron by an electron (an electron by a positron, an electron by a muon) in the pulsed light field may be several orders of magnitude greater than the corresponding...
Resonant two-photon annihilation of an electron-positron pair in the field of a moderately strong circularly polarized wave is investigated theoretically. The partial cross-section is derived. It is shown that the resonant differential cross-section can differ from that in the absence of the external field.
Resonant spontaneous bremsstrahlung by an electron scattered by a nucleus in the field of pulsed light wave is theoretically investigated. The bremsstrahlung cross section contains a resonant peak. It is demonstrated, that the resonant cross section of the spontaneous bremsstrahlung may be several orders of magnitude greater than the corresponding cross section in the external field absence. Obtained...
The resonant scattering of a photon by an electron through direct diagram was studied in the low intense pulsed plane wave. The resonant amplitude and the cross-section were obtained. It is shown that the resonant cross-section is several orders of magnitude greater than the nonresonant one.
We calculated isotropic and anisotropic Bragg interaction geometry in silicon based 2D photonic crystals with square and triangle lattice. Bragg angle vs. acoustic wave frequency dependencies are presented and compared for both structures. Further research aims and expected effects are defined.
Influence of spin-polarization effects on the intensity of synchrotron emission from magnetized electron-positron plasma is discussed. In the plasma generated by pair production spin states have polarization-dependent spin bias, whereas in the case of thermodynamical preparation of spin states they are equally populated. It is shown, that radiation intensities from polarized and unpolarized particles...
An optical amplifier followed by a bistable element has been statistically analyzed before. In this manuscript, output noise analysis represents, then signal to noise ratios (SNR) are calculated either for input or output. It will be shown that noise reduction, can be achieved by a proper selection of parameters.
