“…When organic dyes like coumarins or rhodamines series dissolved in organic solvents and optically excited by laser source, the dye molecules strongly absorb the incident photons and emit high intense laser due to population inversion [5][6][7][8]. If the population inversion is very high, the optical gain should be so high and more enough to produce amplified spontaneous emission (ASE).…”

The spectral characteristics of 1,2,3,8-tetrahydro-1,2,3,3,8-pentamethyl-5-(trifluoromethyl)-7H-pyrrolo[3,2-g]quinolin-7-one (LD-473) were demonstrated in liquid and solid states. For the liquid state, the absorption and fluorescence spectra of the LD-473 in Methyl Methacrylate showed bands at 385 and 420 nm, respectively. LD-473 in the solid state showed one absorption band at 530 nm, while the fluorescence spectra, under low concentration, showed one band at 615 nm. For higher concentrations, the fluorescence bands are shifted to the red. LD-473 in the solid state under an impulse of Nd: YAG laser showed dual amplified spontaneous emission (ASE) peaks at 605 and 650 nm. The longer wavelength coincided with a fluorescence peak while the shorter wavelength is an abnormal peak.

“…The use of solid state dye lasers gets rid of many of the common problems associated with static or flowing liquid systems. The most frequently used polymeric material is polymethylmethacrylate (PMMA) [2]. The low solubility of dye in PMMA causes limitations, which is overcome by introducing modifying additives.…”

“…A review of literature showed that most of the work on dye-doped polymers has been done with Rhodamine dyes [3] and pyromethane dyes. Some works are reported on coumarin dyes [2]. The study of nonlinear refractive index on dye IR140 [4], has been reported.…”

We have investigated third order nonlinear optical properties and spectral characteristics of methylene blue dye in both polymer and liquid mixtures. The spectral characteristics of the dye is studied by recording the absorption and fluorescence spectra of the dye doped in poly(methylmethacrylate) modified with additive n-butyl acetate(nBA) and the dye in MMA and nBA (liquid mixture). The spectral results of the dye doped polymer rod are compared with dye in liquid Mixture. The nonlinear measurements of the dye in liquid and polymer medium were performed using CW He-Ne laser of wavelength 632.8 nm by employing z-scan technique. The dye methylene blue showed a negative nonlinear refractive index.
