Stimulated resonance Raman scattering of Rhodamine 6G

Optics Letters, 1993
Stimulated resonance Raman scattering (SRRS) of Rhodamine 6G (R6G) has been observed in microdroplets. By increasing the R6G concentration and input-laser intensity, SRRS from R6G can be distinguished from the R6G lasing. SRRS can be further amplified by the lasing gain when the SRRS is near the peak of the lasing gain profile.

Optical phase conjugation in aqueous rhodamine 6G solutions and in rhodamine 6G embedded in polyvinyl alcohol films

Canadian Journal of Physics, 1993
Studies on optical phase conjugation by degenerate four-wave mixing in aqueous rhodamine 6G solutions and in rhodamine 6G embedded in polyvinyl alcohol thin films are presented. The experiments were performed at 532 nm using picosecond pulses. Strong nonlinearities were observed in both media for three different polarization configurations of the ...

Aggregate formation of Rhodamine 6G in anisotropic solvents

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2001
The aggregation of Rhodamine 6G in liquid crystalline solutions was studied using polarised spectroscopy and in a guest-host system based on homogeneous-homeotropic alignment. The orientation of the dye molecules (guest) was controlled using an electric field, and this enabled the contrast ratio R of the dye to be obtained by electrically switching ...

Human cell variants resistant to rhodamine 6G

Somatic Cell and Molecular Genetics, 1985
Two variants have been isolated from the cultured human cell line VA2-B which are resistant in vivo to the mitochondrial-specific fluorescent dyes rhodamine 6G and rhodamine 123. Both mutants are cross-resistant to ethidium bromide but are sensitive to both colchicine and chloramphenicol.

Photostability of porous silica – rhodamine 6G hybrid samples

Materials Science and Engineering: C, 2006
Abstract In the last decades solid-state tunable lasers were prepared by embedding dye molecules into sol–gel matrix. The main advantage with respect to the liquid dye solution is the decrease of health and environmental hazards. However the desired dye photostability, which is mainly related to the photochemical degradation of organic molecules in ...

Solvent effects on the gain of rhodamine 6G

Applied Physics, 1980
The effect of solvents on the gain and the peaks of gain spectra is investigated for rhodamine 6G (R6G) under nitrogen laser pumping. The non-specific solute-solvent interaction for R6G is found to be mainly dispersive. Additional shifts produced for R6G in certain solvents are explained as due to hydrogen bonding.

Nanostructured Hybrid Systems with Rhodamine 6G

Journal of Dispersion Science and Technology, 2008
We synthesized hybrid materials by sol-gel process, using: methyltriethoxysilane, tetraetylorthosilicate and vinyltriethoxysilane, in the presence of Rhodamine 6G. It was synthesized as well organic-inorganic hybrids with addition of tetraisopropyl orthotitanate and maleic anhydride UV-VIS spectra of dye show two absorption peaks at 499 nm (dimer) and ...

Quantum control of Rhodamine 6G in solution

Frontiers in Optics, 2006
We present coherent control of dye photoluminescence in solution obtained with a novel, compact, and high-resolution phase modulator in reflective mode. Analysis of the populations used in the optimization process is also presented.

On the mechanism of rhodamine 6G fluorescence quenching

Optics Communications, 1972
Abstract The fluorescence of the widely used TPF dye rhodamine 6G is quenched by photons of the ruby as well as the Nd-glass laser. Taking into consideration the polarisation of the ground- and excited-state absorptions of rhodamine 6G a simple model of quenching results.

Rhodamine 6G laser pumped by cathodoluminescence

Soviet Journal of Quantum Electronics, 1984
Cathodoluminescence from a CdS crystal, generated by the action of high-power short-duration electron beam pulses was used to pump a rhodamine 6G (R6G) laser. Measurements were made of the energy spectrum of the electrons in the beam exciting the CdS crystal, of the cathodoluminescence spectrum of CdS, of the absorption and emission spectra of the dye,
