We report optically pumped lasing action near 650nm of 1-amino-2-methylanthraquinone (known as Disperse Orange 11 or DO11) in the common laser dye solvents dimethylformamide and dimethylsulfoxide. Amplified spontaneous emission (ASE) was studied under second-harmonic Nd:YAG laser excitation in a transverse pumping configuration. ASE conversion efficiency is found to be comparable to other laser dyes. Photodegradation of dye solution in a micro-cuvette was investigated. While DO11 in poly(methyl…

Two-photon fluorescence measurements of reversible photodegradation in a dye-doped polymer.
TLDR
The energy dependence suggests that photodegradation is a linear process, while recovery is entropic, which could be useful to high-intensity devices such as two-photon absorbers, which can be used in many applications.
