چکیده
We report on the lasing action of modified rhodamine 6G dyes copolymerized with methacrylic monomers. The laser samples were transversely pumped with a N2 laser at 337 nm. Lasing efficiencies similar to those found for rhodamine 6G in ethanol solution have been achieved. Important increases in photostability, with lifetimes in excess of 20 000 shots at 2 Hz, have been obtained. By using a rotating mechanism, a stable output with no sign of degradation after half a million shots has been demonstrated. © 1996 American Institute of Physics. @S0003-6951~96!04605-7#

High-repetition-rate polymeric solid-state dye lasers pumped by a copper-vapor laser
We report on the laser action of pyrromethene 567 incorporated into polymeric matrices and pumped longitudinally with the green line of a copper-vapor laser. When the dye was dissolved in a copolymer of methyl methacrylate and pentaerythritol triacrylate, 290 mW average power at 1 kHz ~37% lasing efficiency! was obtained. The laser output decreased to 150 mW after 30 min irradiation time (1.831...

This paper presents wavelength configurable on-chip solid-state ring lasers fabricated by a single-mask standard lithography. The single- and coupled-ring resonator hosts were fabricated on a fused-silica wafer and filled with 3,3'-Diethyloxacarbocyanine iodide (CY3), Rhodamine 6G (R6G), and 3,3'-Diethylthiadicarbocyanine iodide (CY5)-doped polymer as the reconfigurable gain media. The recorded...
متن کاملSelective mode excitation in dye-doped DNA polyvinyl alcohol thin film.
A solid-state laser based on a dye-doped deoxyribonucleic acid (DNA) matrix is described. A thin solid film of DNA has been fabricated by treating with polyvinyl alcohol (PVA) and used as a host for the laser dye Rhodamine 6G. The edge emitted spectrum clearly indicated the existence of laser modes and amplified spontaneous emission. Lasing was obtained by pumping with a frequency-doubled Nd:YA...
متن کاملSTUDIES ON DYE DOPED POLYMERS Abstract
The fluorescence and amplified spontaneous emission characteristics of rhodamine 6G impregnated in polyacrylamide is reported in this chapter. Using amplified spontaneous emission gain radiative and related properties of this dye doped matrix was measured. It was found that photostability of rhodamine 6G is unusually high in this matrix compared to other polymer hosts like polyrnethylmethacrylate.
