Characteristics of optical limiting in media with nonlinear absorption and scattering

Zelensky, S.E.; Kolesnik, O.S.; Kopyshinsky, O.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)

A comparative study is performed for characteristics of optical limiting in the media with nonlinear absorption and scattering with the use of nanosecond-scale laser pulses. Two methods are proposed to analyze of experimental ...
Effect of non-linear absorption on characteristics of laser-induced luminescence

Zelensky, S.E.; Okhrimenko, B.A. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)

This paper deals with the methodology of laser-induced luminescence at high excitation levels. For a case when a photodetector collects integral (over the volume) luminescence power, a method is proposed for processing the ...
Laser- and g-induced optical absorption of indium-doped sodium-borate glass

Kopyshinsky, A.V.; Okhrimenko, B.A.; Zelensky, S.E.; Danilchenko, B.O.; Shakhov, O.P. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2002)

The laser- and g-induced absorption spectra of indium-doped sodium-borate glass are investigated experimentally. The spectra are interpreted with the use of a model that includes three types of indium centers.
Laser-induced incandescence in aqueous carbon black suspensions: the role of particle vaporization

Rulik, Ju.Ju.; Mikhailenko, N.M.; Zelensky, S.E.; Kolesnik, A.S. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2007)

Non-linear properties and the kinetics of laser-induced incandescence in aqueous carbon black suspensions are investigated. For explanation of the observed properties, a model, which takes into account a decrease of the ...
Laser-induced incandescence of borate glass doped with carbon microparticles

Kopyshinsky, A.V.; Lazorenko, Ya.P.; Zelensky, S.E. (Functional Materials, 2011)
Laser-induced incandescence of silicon surface under 1064-nm excitation

Kopyshinsky, A.V.; Zelensky, S.E.; Gomon, E.A.; Rozouvan, S.G.; Kolesnik, A.S. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2012)

Laser-induced incandescence (LII) of silicon surface is investigated under the excitation by a Q-switched YAG:Nd laser. With the increase of laser irradiation dose, the increase of LII signal is observed, which is attended ...
Laser-induced non-linear light scattering in a suspension of black-body particles

Zelensky, S.E. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)

Characteristics of non-linear scattering of powerful pulses of Q-switched YAG:Nd³⁺ laser in an aqueous suspension of submicron-sized black-body particles has been investigated. Proposed is a model describing the results ...
Luminescent properties of fine-dispersed ZnS:Cu prepared using self-propagating high-temperature synthesis

Bacherikov, Yu.Yu.; Zelensky, S.E.; Zhuk, A.G.; Semenenko, N.A.; Krylova, O.S. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2014)

Fine-dispersed ZnS doped with Cu was prepared using self-propagating hightemperature synthesis. In the photoluminescence excitation spectra, the blue shift of the host lattice excitation peak is observed for powder ZnS:Cu ...
Non-uniformity of cross-beam laser power distribution as a source of errors in non-linear spectroscopy

Zelensky, S.E. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)

We investigated errors arising in calculations of optical signals in non-linear laser spectroscopy due to neglection of non-uniformity in cross-beam laser power distribution. The following three cases of non-linear emission ...
Optical transmittance of carbon suspensions in polymer matrixes under powerful pulsed laser irradiation

Zelensky, S.E.; Kopyshinsky, O.V.; Garashchenko, V.V.; Kolesnik, A.S.; Stadnytskyi, V.M.; Zelenska, K.S.; Shynkarenko, Ye .V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2010)

The effect of optical limiting is investigated in the suspensions of carbon microparticles in aqueous gelatin gel and epoxy resin. Both transient and permanent changes of optical transmittance are observed after the ...
