Abstract Polystyrene (PS)-diphenyloxazole (PPO) nanoparticles with attached cross-linked poly-N-isopropylacrylamide (PNIPAM) chains were obtained resulting in PS-PPO-PNIPAM hybrid nanosystems (NS). Fluorescence spectra of chlorin e6 added to PS-PPO-P

Random lasing (RL) in disordered active media can initiate stimulated Raman Scattering (SRS). We have found the optimal condition of SRS-RL coupling, which is perspective for Raman spectroscopy applications.

An iterative method is developed to obtain vibrational spectra of laser organic dyes from their secondary radiation spectra in multiple-scattering media, which manifests as a result of coupled process of chaotic generation (CG) and stimulated Raman s

We report waveguide mode lasing in the mesoscopic ordered organic-inorganic SiO 2 and TiO2 films doped by Rhodamine 6G formed of the glass substrate. Inorganic matrices had a refractive index lower 1,499) and higher (1,565) then the index of glass su

Stimulated Raman scattering (SRS) of a mixture of rhodamine 6G and pyrromethene 605 laser dyes in vesicular films is studied. It is shown that a peculiar interaction of dyes occurs under conditions of multiple scattering of light from vesicles. This

It is shown that reabsorption of the luminescence radiation in the range of its overlapping with the absorption spectrum and the following reemission to a long-wavelength range may noticeably affect the process of stimulated Raman scattering (SRS) in

A method is described for deriving Raman spectra of organic dyes from their random lasing spectra. The method was tested using Rhodamine 6G. The Raman spectrum obtained for this dye agrees well with the spectra measured by standard techniques but is
