Notes:
Two-photon pumped (TPP) frequency-upconverted lasing properties of a partially cross-linked fluorescent polymer are reported. This lasing medium is a cross-linked homogeneous copolymer with two major compounds: the chromophore, 4-[bis(2-hydroxyethyl)amino]-N-methylstilbazolium iodide, and the monomer, 2-hydroxyethyl methacrylate. The spectral, temporal, and spatial structures as well as the output/input characteristics of the TPP cavity lasing were measured using a 13 mm long polymer rod. The net conversion efficiency from the absorbed 1064 nm pump pulse energy to the ∼606 nm upconverted cavity lasing energy was found to be ∼4%. © 1997 American Institute of Physics.
