Abstract
The third order nonlinear susceptibility, two photon absorption coefficient, 13, and linear absorption coefficient, a, for some rare-earth cyclopentadienyl compounds and dithiolene complexes have been measured. Resonantly enhanced x3 coefficients of up to 1011esu for dilute solutions have been determined. Trade off in the size of the nonlinear susceptibility, with loss, in materials with low two photon absorption leads us to believe that Stegeman1'2 figures of merit acceptable for some all-optical switching devices are achievable with such materials.Keywords
