B. Sahraoui et al., NONLINEAR-OPTICAL PROPERTIES OF NEW HYPER-TETRATHIAFULVALENE DERIVATIVES - SATURABLE ABSORPTION AND DEGENERATE 4-WAVE-MIXING, Optics communications, 135(1-3), 1997, pp. 109-115
The results of absorption saturation and the efficiency of degenerate
four-wave mixing measurements at 532 nm are reported on two novel orga
nic compounds: hyper-tetrathiafulvalene (HTTF) derivatives dissolved i
n tetrahydrofuran (THF). The cross-sections for ground state and excit
ed state absorption, the relaxation time and the chi([3]) values are e
stimated.
