Abstract
An acceptor/acceptor conjugated oligomer chromophore, Naval Research Laboratory 303 (NRL303) was rigorously studied in a polymethyl methacrylate (PMMA) matrix. Linear optical studies were conducted with the third harmonic (THG) of an Nd:YAG laser (355nm) and nonlinear studies with the second harmonic (SH) (533nm) and the optical parametric amplification (OPA) wavelengths from a tunable Ti:Saphire laser. The chromophore-doped PMMA matrix strongly fluoresces and is a source of efficient blue light centered around 460nm from amplified spontaneous emission (ASE). Blue emission from this chromophore has higher gain, efficiency and two-photon absorption cross-section ([beta]2) than Rhodamine 6G (Rh6G) a benchmark in laser dyes in a solid state system. This chromophore has been successfully made into a blue ASE polymer-fiber light source. A design factor [beta]df is introduced to investigate the design strategy for making molecules with large TPA cross-section for this class of donor/donor (D/D), acceptor/acceptor (A/A) and acceptor/donor(A/D)chromophore-linked [pi]-centers.
