“…Several studies on photo-induced bleaching of organic dyes impregnated in solid matrices have been reported during the past few decades [1][2][3][4][5][6][7][8][9][10]. Such studies have great importance due to the various applications of these materials, such as for active laser elements, passive Qswitches, optical data storage, photonic displays, optical waveguides etc.…”

Abstract. The photobleaching of the lasing dye Rhodamine 6G embedded in the solid matrix poly(methyl methacrylate) was investigated using a photoacoustic technique. Chopped laser radiation from an argon ion laser at four different wavelengths was used for the study. Experimental results indicate that the photobleaching rate is directly proportional to the incident laser power while it decreases with increase in concentration of the dye molecules. In the present case we have not observed any dependence of photobleaching on the chopping frequency. One-photon absorption is found to be responsible for the photobleaching of the dye within the selected range of laser power.

“…[9]. Dyumaev et al [5] observed that the photobleaching rate was linearly dependcnt on radiation intensity J and that at relatively low radiation intensity (1<10(\ W/cm2) the destruction occurs from first excited state (singlet or triplet) electron state. At higher intensities (1) 10 7 W/cm 2 ) saturation of SO-SI transtion (So is the ground state and S I is the excited singlet level) is enhanced.…”

“…The most frequently used polymeric material is polymethy 1 methacrylate (PMMA) because of its best optical transparency and resistance to laser damage. The low solubility of the laser dyes in PMMA causes some limitations like decrease in luminescence quantum yield and laser conversion efficiency [5], which is overcome by introducing modifying addtives [6]. Most of the work in dye doped polymer was done with dyes of rhodamine family, mainly with rhodamine 6G(Rh6G) emitting in yellow and red regions of the spectrum.…”

Solid state dye doped polymer is an attractive alternative to the conventional liquid dye solution. In this paper, the laser characteristics of LD490 (LD490) doped polymethy J methacrylate (PMMA) rods modified with dioxane are studied under third harmonic Nd : YAG laser excitation ill a transverse l'umP configuration and the variation of gain coefficient of the dye in solid mediumfor different pump powers is studied.The photobleaching of dye molecule in polymer medium under third harmonic Nd : YAG laser excilion is also studied for various pump enel'gy.

“…Elastomers and plasticized polymers have low modulus of elasticity, and hence increased radiation resistance. The improvement of the radiation resistance of widely used polymethyl methacrylate (PMMA) media is often achieved by its modifying with low molecular additives [4,5]. However such plasticization is accompanied by a deterioration of the mechanical properties and shape stability of PMMA based laser elements According to [6][7][8] Ph-510 can interact with components of the reaction mixture to form urethane groups [6].…”

The dynamic characteristics of polyurethane matrix of dye laser solid-state active elements

et al. 2016

View full text Add to dashboard Cite

Investigations of polyurethane matrices for solid-state laser active elements showed that comparison of chain mobility and permeability for low molecular substances of polyurethanes based on glycol and diisocyanate components of various structures allows predict their radiation resistance and choose optimal chemical composition of polyurethane. The correlation was shown of polyurethane dynamic properties with values of their elastic modulus and laser damage threshold under pulsed laser irradiation as well as the weak influence of phenalenone dyes introduction on the above characteristics.
