Near-infrared dye having a large ultrafast third-order susceptibility.
Efficient degenerate four-wave mixing of 160-psec infrared light pulses at lambda = 1.064 microm in solutions of a new dye that absorbs between 1.0 and 1.6 microm is reported. A Kerr-like third-order susceptibility of X((3))(xyyx) = 8 +/- 3) x 10(-12) esu with a decay time of less than 50 psec is observed in various solvents.
