“…Nonlinear effects like SBS arise due to the density of radiation in this solution [3]. The similar density of radiation is reached due to a combination of the luminescence fields and laser radiation [2] giving the characteristic peak. The modal frequency of this peak depends on the type of DNA accordingly.…”

“…The utilization of Raman scattering spectroscopy technique requires transferring an enormous amount of energy for extracting an informative signal, which is considerably lower than the noise [4]. At present laser-based technology requires no consumables, or reagents are currently being developed [2]. A new method for detection of live or dead pathogens in water is described below.…”

Hygienic standards to the quality of potable water require continuous monitoring of the absence of pathogenic microorganisms directly in water flow. Despite a great number of laboratory devices for checking the quality of potable water, there are no express analyzers for monitoring of pathogenic organisms, which could be embedded directly into the automatic checkout systems. The reasons of it are low concentration of pollutions and the presence of additional effects, which impede automatic data processing. The new method, the express analysis of pathogens in water, was developed. It shall be mentioned that the proposed method of express diagnostics allows detection of infectious agents in the water in minutes based on nonlinear effects. This research has, hopefully, laid the foundation for development of a prototype for determination of the content of the genetically modified soy in meat products. The inventive methods can be recommended for DNA diagnostics in medicine ,veterinary sciences and insanitation. The main advantage of this method is that there is no need for DNA isolation. It is sufficient to create a suspension of the product by centrifugation.

“…In case of coherent pumping the SBS is observed at the density fluctuations [8,9]. The stationary inhomogeneities in no way influence the acoustic waves excitation under coherent pumping, since a permanent generation of these waves at the same place (near a local inhomogeneity) results, due to the interference, in waves extinguishing, and the SBS does not appear.…”

Nanosecond pulses of broadband collimated generation in the wavelength region of 1.0–1.06 μm were observed at focusing the pump radiation from LiF:F2+ color center laser onto the plates from YAG:Yb crystal or Yb-doped phosphate glass. Spectra of the widths up to 200 Å for YAG:Yb and up to 500Å for glass were registered. The angular divergence (10-3–10-4 rad) of broadband radiation from the emitting area of 100–200 μm in diameter was by 1–2 orders of magnitude smaller than the diffraction limit corresponding to this area. Physical mechanism responsible for the occurrence of highly collimated broadband lasing under stimulated Brillouin scattering (SBS) of the pump radiation in the active medium is discussed.

An analytical investigation is made of the stimulated Brillouin scattering of a plane polarized intense electromagnetic wave propagating parallel to the applied magnetic field in a n-type semiconducting plasma with high dielectric constant. The general dispersion relation is obtained and solved for both, the cases of scattered electromagnetic waves (i.e. in the case of left hand and right hand circularly polarized waves) to study the threshold condition and the growth rate of the unstable Brillouin mode at a pump amplitude well above the threshold. It is found that the threshold pump amplitude is independent of applied magnetic field and is the same for both types of polarization. The growth rate of the unstable Brillouin mode has linear dependence on the magnetic field. Numerical estimations are made for n-BaTiO, irradiated with a pulsed 10.6 Fm COz laser to obtain the necessary electric field.In einem n-leitenden Halbleiterplasma mit hoher Dielektrizitatskonstante wird die stimulierte Brillouinstreuung einer intensiven linear-polarisierten elektromagnetischen Welle untersucht, die sich parallel zum angelegten Magnetfeld ausbreitet. Die allgemeine Dispersionsbeziehung wird erhalten und sowohl fur den Fall gestreuter elektromagnetischer Wellen (d. h. fur den Fall von links-und rechtszirkular polarisierter Wellen) fur die Untersuchung der Schwellbedingung als auch fur die Wachstumsrate der instabilen Brillouinmode bei einer Pumpamplitude weit oberhalb der Schwelle gelost. Es wird gefunden, da13 die Schwellenpumpamplitude unabhangig vom Magnetfeld und fur beide Polarisationstypen dieselbe ist. Die Wachstumsrate der instabilen Brillouinmode besitzt eine lineare Abhangigkeit vom Magnetfeld. Numerische Berechnungen werden fur n-BaTiO, durchgefuhrt, das mit einem gepulsten 10,6 pm-C0,-Laser bestrahlt wird, um das notwendige elektrische Feld zu erhalten.
