摘要:

Quantitative studies of third‐harmonic generation in the all‐trans &bgr;‐carotene molecule and of third‐harmonic generation and the optical Kerr effect in &bgr;‐carotene glass are reported. The large values of the optical nonlinearities are attributed to the broadly delocalized &Pgr; electrons.
