“…Here, the optical and laser properties of LD-473 showed a large red shift after solidification; while in the previous studies, no shift appears in the spectrum after solidification [5,21,22]. When 1.8 mM of LD-473 as solid state was excited by Nd: YAG laser pulse of 6 mJ pulse energy, it gives ASE emission.…”

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.

“…Bleaching of the dye occurs when the molecules are excited. 21 This means that as the population inversion increases the bleaching of the dye will also increase, thereby leading to shorter lifetime of the dye for higher threshold. The proportionality between lifetime and 1/threshold is clarified by a linear fit to the measurement points in Fig.…”

The influence of index contrast variations for obtaining single-mode operation and low threshold in dye doped polymer two dimensional photonic crystal (PhC) lasers is investigated. We consider lasers made from Pyrromethene 597 doped Ormocore imprinted with a rectangular lattice PhC having a cavity in the middle of the crystal structure. We demonstrate that the index contrast, neff,high/neff,low, is an essential parameter for achieving low threshold, and we identify a trade-off between low threshold and single-mode operation.

“…Solid state dye lasers were realized already in 1967 by Soffer and McFarland 2 and by Peterson and Snavely, 3 who demonstrated stimulated emission from a polymer matrix doped with a laser dye. A review on the further development of solid state polymeric dye lasers is given by Singh et al 4 Methods for improving the efficiency and lifetime of these devices have attracted much attention. [5][6][7] Low cost, maintenance-free polymer based solid state lasers could find applications within communication and sensing systems.…”

“…The Rhodamine-doped PMMA is heated during fabrication, and since most organic dyes are observed to be degraded when heated, 4,23,24 this has been investigated. Rhodamine 6G is available in several versions, and the most commonly used is Rhodamine 6G Cl.…”

We present a solid state polymer microcavity dye laser, fabricated by thermal nanoimprint lithography (NIL) in a dye-doped thermoplast. The thermoplast poly-methylmethacrylate (PMMA) is used due to its high transparency in the visible range and its robustness to laser radiation. The laser dye is Rhodamine 6G ClO 4 . This dye is shown to withstand temperatures up to 240°C without bleaching, which makes it compatible with the thermal nanoimprint lithography process. The 1.55 m thick dye-doped PMMA devices are fabricated on a SiO 2 substrate, yielding planar waveguiding in the dye-doped PMMA with two propagating TE-TM modes. The laser cavity has the lateral shape of a trapezoid, supporting lasing modes by reflection on the vertical cavity walls. The solid polymer dye lasers emit laterally through one of the vertical cavity walls, when pumped optically through the top surface by means of a frequency doubled, pulsed Nd:YAG laser. Lasing in the wavelength region from 560 to 570 nm is observed from a laser with a side-length of 50 m. In this proof of concept, the lasers are multimode with a mode wavelength separation of approximately 1.6 nm, as determined by the waveguide propagation constant(s) and cavity dimensions. The stamps used in this work were fabricated by UV-lithography, limiting the lateral dimensional control of the devices. The resolution of NIL is ultimately limited by the quality of the stamps. Using electron beam lithography for stamp fabrication, the NIL process presented here offers the possibility for adding mode-selecting elements, e.g., diffractive-or sub-wavelength optical elements.
