Abstract :
Summary form only given. A one-dimensional conjugated polymer that exhibits a large optical nonlinearity in the ground state is targeted as a new system for the optical pumping enhancement of third order optical nonlinearity. Femtosecond optical pumping of a chloroform solution of poly(dodecylthiophene) was revealed to produce a tremendous gain of the third order nonlinearity using degenerate four-wave-mixing measurements.
