Nonresonant χ1111(3) obtained by nearly degenerate four-wave mixing using chirped-pulse technology

Abstract

Picosecond chirped-pulse technology is used to generate two spectrally separate, time-synchronized pulses for chi((3)) measurements by nearly degenerate four-wave mixing. Near 1053 nm, nonresonant relative measurements of chi((3))(1111)are carried out on three model substances, nitrobenzene, alpha chloronaphthalene, and 4'-decyloxynaphthyl-1'-(4-decyloxybenzoate). Their chi((3)) values are normalized to CS(2).
