Comparative studies of eye-safe intracavity and extracavity optical parametric oscillators with an unstable telescopic cavity
Autor: V. V. Rukhovets, Nikolai S. Kazak, A. I. Vodchits, V. K. Pavlenko, V. I. Pokryshkin, V. I. Dashkevich, I. P. Petrovich, V. A. Orlovich
Publikováno v: Journal of Applied Spectroscopy. 73:604-612
We have experimentally studied the lasing characteristics of an eye-safe optical parametric oscillator (OPO) with an unstable telescopic cavity when it is placed inside (intracavity OPO) and outside (extracavity OPO) the plane-parallel cavity of a pu

We have studied an optical parametric oscillator (OPO) with an unstable telescopic cavity, placed inside the cavity of an actively Q-switched multimode Nd3+:KGW pump laser. We used a KTP crystal as the nonlinear medium for the OPO. We have compared t

Background noise suppression in wide-band lasers with a nonlinear mirror in the cavity
Autor: V. K. Pavlenko, A. A. Ryzhevich, Nikolai S. Kazak, E. G. Katranzhi
Publikováno v: Journal of Applied Spectroscopy. 67:226-229
An effective method for suppressing free background generation is proposed. It is based on polarization separation of the narrow-band output radiation of a controlled laser with a nonlinear mirror in the cavity. An increase in the integral ratio betw

Ultrasonic beam focussing in ferroelectric ceramics by application of a non-uniform electric field
Autor: V. N. Belyi, A. G. Mashchenko, V. K. Pavlenko, F. M. Severin, Nikolai S. Kazak
Publikováno v: Ultrasonics. 33:295-299
A new solution to the problem of controllable focussing of ultrasonic beams is given. It results from the fact that the application of a non-uniform electric field, of a special configuration, in ferroelectric ceramics causes a quadratic change of th

Spectral transmission of a wide-aperture bragg acoustooptical paratellurite filter
Autor: A. S. Lugina, A. V. Nadenenko, V. B. Voloshinov, Yu. A. Sannikov, V. K. Pavlenko, Nikolai S. Kazak
Publikováno v: Journal of Applied Spectroscopy. 52:209-213
In this paper we study the spectral characteristics of a wide-aperture noncollinear filter based on a paratellurite crystal and the dependence of the transmission linewidth on the size of the angular aperture. The vector diagram of the AO interaction

Publikováno v: The Journal of membrane biology. 197(3)
We used the patch-clamp technique to identify and characterize the electrophysiological, biophysical, and pharmacological properties of K(+) channels in enzymatically dissociated ventricular cells of the land pulmonate snail Helix. The family of outw

[Spatial organization of colonies of dimorphic micromycetes]
Autor: L K, Panina, E V, Bogomolova, V K, Pavlenko
Publikováno v: Biofizika. 45(5)
The peculiarities of the formation of colonies of dimorphous epilithic fungus Phaeococcomyces de Hoog isolated from marble were studied. The data obtained can be used for modeling the formation of colonies of dimorphous microscopic fungi.
