Abstract

The two-photon absorption and two-photon pumped (TPP) frequency-upconverted green lasing properties of a new dye, 1-(N-methyl-4-pyridinio)-2-(N-methylpyrrol-2-yl)ethene triflate (abbreviated as M-PPE) have been experimentally investigated. This new dye exhibits a low lasing threshold and high lasing efficiency when pumped with a 800-nm pulsed laser beam. The spectral, temporal, and spatial structures as well as the output/input characteristics of the TPP cavity lasing were measured using a 1 cm-path quartz cuvette filled with the M-PPE solution in dimethyl sulfoxide. The net conversion efficiency from the absorbed 800-nm pump pulse energy to the ∼ 543-nm upconverted cavity lasing energy was found to be as high as ∼ 11%.
