The all-optical poling of polymers is a key process for the optical control of plastic materials for second order nonlinear optical effects. It is based on the photochromic behavior of dyes submitted to bi-color exciting laser beams. In order to achi

Two-photon absorption in organic dyes can be enhanced by orders of magnitude in particular situations. An original model accounting for an enhanced nonlinear absorption in concentrated interacting dye solutions is presented. The related nonlinear abs
