Third-Order Optical Nonlinearities of Singlewall Carbon Nanotubes for Nonlinear Transmission Limiting Application

摘要

Third-order nonlinear susceptibility of single wall carbon nanotubes thin film was measured to be approximately 1.4 x 10(exp -16) sq m/V2. The nonlinear transmission limiting threshold of carbon SWNT was approximately 20 MW/sq cm with visible and nanosecond laser excitation.
