Autor: Branislav M. Jelenkovic, Branislav Salatić, Dejan Pantelić, Aleksander G. Kovačević, Borislav Vasić, Marina M. Lekić, Suzana Petrović, Radoš Gajić

Publikováno v: Optical and Quantum Electronics

The occurrence of laser-induced periodic surface structures (LIPSS) has been known for a while. Multilayer thin films, like Al/Ti, are suitable for LIPSS formation and attractive for applications—due to their wearing behavior and corrosion resistan

Solitons generated by self-organization in bismuth germanium oxide single crystals during the interaction with laser beam

Autor: Vladimir Skarka, Nebojša Romčević, Marina M. Lekić, Aleksander G. Kovačević, Boban Zarkov

Publikováno v: Optical and Quantum Electronics. 50

We present here the experimental, theoretical, and numerical investigations of Kerr solitons generated by self-organization in black and yellow high quality bismuth germanium oxide (Bi12GeO20) single crystals. A picosecond laser beam of increasing po

International audience; We propose a complex Ginzburg-Landau equation (CGLE) with localized linear gain as a two-dimensional model for pattern formation proceeding via spontaneous breaking of the axial symmetry. Starting from steady-state solutions p

Raman–Ramsey electromagnetically induced transparency in the configuration of counterpropagating pump and probe in vacuum Rb cell

Autor: Branislav M. Jelenkovic, Dragan V. Lukić, Marina M. Lekić, Milan Radonjić, Zoran D. Grujić, I. S. Radojičić

Publikováno v: Journal of the Optical Society of America B. 32:426

Counterpropagating, spatially separated hollow pump and coaxial probe laser beams generate narrow Zeeman electromagnetically induced transparency (EIT) resonances in the vacuum Rb cell. The lasers are locked to D2 line transition Fg=2→Fe=1 of Rb87.

Sub-Doppler absorption narrowing in V, A and N-type atom at intense laser fields

Autor: Marina M. Lekić, Aleksandar J. Krmpot, B. M. Jelenković, Aleksander G. Kovačević, Bratimir Panić, Dejan Pantelić, D. Lukić

Publikováno v: 13th International School on Quantum Electronics: Laser Physics and Applications.

Electromagnetically induced transparency and absorption is observed in a transmission of the coupling laser, locked to transition between hyperfine levels of the ground and excited states of 85 Rb. The transmission was monitored in a V, Λ and N-type
