New Inequality for Density Matrices of Single Qudit States
Journal of Russian Laser Research - Tập 35 - Trang 457-461 - 2014
Vladimir N. Chernega, Olga V. Man’ko, Vladimir I. Man’ko
Using the monotonicity of relative entropy of composite quantum systems, we obtain new entropic inequalities for arbitrary density matrices of single qudit states. Examples of qutrit state inequalities and the “qubit portrait” bound for the distance between the qutrit states are considered in explicit form.

THG in dielectrics using low-energy tightly-focused ir femtosecond laser: third-order nonlinearity measurements and the evolution of laser-induced plasma
Journal of Russian Laser Research - Tập 30 - Trang 599-608 - 2009
V. M. Gordienko, N. G. Khodakovskij, P. M. Mikheev, F. V. Potemkin, K. Ju. Zubov
The third-order nonlinearity x (3) and other optical properties of LiF, CaF2, fused silica, and free standing polymeric thin film are studied using a diagnostic technique based on the third-harmonic generation of tightly-focused femtosecond Cr:forsterite laser radiation. Time-resolved measurements of the plasma evolution in the bulk of a fused silica sample are performed by...... hiện toàn bộ
Diode-End-Pumped Narrow-Linewidth Tm:YLF Laser with a Volume Bragg Grating and Double Fabry–Pérot Etalons
Journal of Russian Laser Research - Tập 42 - Trang 171-174 - 2021
Zhou Guanlong, Li Yue, Hu Ruiyang, Liu Jingliang, Chen Xinyu
A 2 μm laser has important applications and prospects in various fields such as LIDAR, material processing, environmental monitoring, and space communication, as well as fundamental researches. Being designed for the room-temperature operation, our Tm:YLF laser with L flat concave resonator incorporates a laser-diode end-pump setup, in which a volume Bragg grating and double Fabry–Pérot etalons se...... hiện toàn bộ
Wander of a Gaussian-Beam Wave Propagated Through a Non-Kolmogorov Turbulent Atmosphere
Journal of Russian Laser Research - Tập 35 - Trang 416-423 - 2014
Wenhe Du, Jingxuan Yang, Zhongmin Yao, Junguo Lu, Daosen Liu, Quanling Cui
Both increasing experimental evidence and some results of theoretical investigation have shown that there exist two kinds of turbulence in the aerosphere, Kolmogorov and non-Kolmogorov turbulence. Thus, it is necessary to improve the theory of optical wave propagation through atmospheric turbulence, namely, study the laser-beam propagation in non-Kolmogorov turbulence, before analyzing the joint i...... hiện toàn bộ
Light absorption by ultrasmall silver particles
Journal of Russian Laser Research - Tập 5 - Trang 165-166 - 1984

Experimental investigation of chemical oxygen-iodine laser
Journal of Russian Laser Research - Tập 15 - Trang 213-242 - 1994
N. P. Vagin, D. G. Karapetyan, A. F. Konoshenko, P. G. Kryukov, V. S. Pazyuk, V. N. Tomashov, N. N. Yuryshev
Results of an experimental investigation of a chemical oxygen-iodine laser (COIL) are presented. We determine the factors influencing the efficiency of a chemical singlet-oxygen generator (SOG) of the bubbler type operating on the chlorination of an alkaline solution of oxygen peroxide. We describe SOG constructions. A cw COIL with output power up to 400 W is developed on the basis of the investig...... hiện toàn bộ
Quantum character of optical breakdown of gases in the visible and UV bands of the spectra

Coherent effects in two-level amplifying and SRS-active media
Journal of Russian Laser Research - Tập 10 - Trang 145-156 - 1989
É. M. Belenov, P. G. Kryukov, A. V. Nazarkin, A. N. Oraevskii, A. V. Uskov
Some results are reported on coherent propagation of optical pulses. In particular, a solution is presented of the Maxwell-Bloch equations for the case of amplification of high-power pulses with varying carrier frequency but with constant number of photons in the pulse.
Symplectic tomography of the Jaynes-Cummings model
Journal of Russian Laser Research - Tập 21 - Trang 205-213 - 2000
A. B. Klimov, V. I. Man'ko
We derive equations describing quantum evolution for the classical-like tomographic-probability-distribution function for the Jaynes-Commings model. Different representations for the field part of the total density matrix are considered.
