Third-order optical nonlinearities of metallotetrabenzoporphyrins and a platinum poly-yne.
The third-order optical nonlinearities of two metallotetrabenzoporphyrins and a platinum poly-yne dissolved in tetrahydrofuran were measured by using picosecond and nanosecond laser pulses. The pulse-width-dependent measurements indicated that excited-state absorption was present in both classes of material along with non-resonant two-photon absorption.
