Abstract
Two-photon chromophores developed by the Air Force Research Laboratory were used to internally generate visible light at 475 nm which, in turn, activates a photoinitiator enabling polymerization to occur. The advantage of the technique is two folds. First, a greater depth of penetration can be achieved in organic materials with the use of infrared light to produce thicker polymer structures. The second advantage is the quadratic dependence of the nonlinear optical chromophore on the activating light source, which means there is the potential for fabrication of polymeric structures with greater spatial resolution.
