Abstract
A new dye, trans-4-[p-(pyrrolidinyl)styryl]-N-methylpyridiniuum iodide, has been synthesized, and the two-photon-absorption (TPA), TPA-induced frequen cy upconversion emission, and two-photon-pumped (TPP) frequency upconverted lasing properties of this new dye were experimentally studied. This new dy e has a moderate TPA cross section of sigma (2) = 5.7 x 10(-48) (cm(4) s(-1 ))/photon at 1064 nm but exhibits high lasing efficiency. The slope efficie ncy of the TPP cavity laser with this new dye as the laser medium is 1.6%. (C) 2001 Optical Society of America.
