  New systems are required for optical limiting against broadband laser pulses.
We demonstrate that the association of non-linear scattering from single-wall
carbon nanotubes (SWNT) and multiphoton absorption (MPA) from organic
chromophores is a promising approach to extend performances of optical limiters
over broad spectral and temporal ranges. Such composites display high linear
transmission and good neutral colorimetry and are particularly efficient in the
nanosecond regime due to cumulative effects.
