ROLE OF AXIONS IN THE FORMATION OF FREQUENCY AND ANGULAR SPECTRA OF LASER RADIATION PROPAGATING IN A DISPERSIVE MEDIUM
Autor: V. E. Ogluzdin
Publikováno v: Journal of Applied Spectroscopy. 89:890-893
A variant of the interpretation of the spectrum broadening and the change in the angular characteristics of the light beam at the exit of the dispersive medium is proposed. The role of axions responsible for changes in the spectral and angular charac

Publikováno v: Optical Materials. 30:260-263
Experimental results are presented related to the nonlinear optical response of silicon nanocrystals under visible nsec laser excitation. The nanocrystals were examined in water and glycerol suspensions and as was shown, they exhibit saturable absorp

Direct observation of the shift of the 4P(1/2) electronic level in atomic potassium vapor upon the saturation (redistribution of the population of levels) of the 4S(1/2)-4P(3/2) transition under the conditions for nearly resonant laser pumping
Autor: V. E. Ogluzdin
Publikováno v: Laser Physics. 16:1178-1183
The saturation of the population of transitions can cause the shift of electronic levels of an atomic shell in addition to the Stark effect. Experimental results obtained for atomic potassium vapor and demonstrating a shift of the 4P(1/2) electronic

Optical properties of multishelled amorphous silicon nanoparticles
Autor: S. Vasil'chenko, S. Korovin, V. E. Ogluzdin, V. I. Pustovoi
Publikováno v: SPIE Proceedings.
Adsorbed metal on the semiconductor surface change strongly the optical properties of the interface due to the charge distribution. This effect is more important for nanoparticles. In this paper we present the experimental results and analysis of amo

Overlight and tunneling photons in laser beam in medium of two-level atoms
Autor: V. E. Ogluzdin
Publikováno v: SPIE Proceedings.
There is an interest in consideration of the propagation of the Gaussian monochromatic light beams through a cell filled with the medium of two-level atoms (in our case, the atomic potassium vapor), which has (at small detuning from resonant transiti

Optical properties of amorphous silicon nanoparticles
Autor: V. E. Ogluzdin, Vladimir I. Pustovoi, S. B. Korovin
Publikováno v: SPIE Proceedings.
In this paper we present the experimental results and analysis of amorphous silicon nanoparticle's (a-n-Si) optical properties. The optical properties of individual particles of a-n-Si imbedded in glycerol, water and conglomeration ofparticles have b
