Abstract :
This paper reports the photodegradation and recovery of two-photon fluorescence (TPF) in the chromophore AF455 doped in poly(methyl methacrylate) (PMMA) polymer, known to have a large two-photon absorption cross-section and a promising optical material for many applications. The self-healing of amplified spontaneous emission (ASE) in the DO11 system is also analysed.
