چکیده مقاله
Two photon polymerization 2PP has emerged as a unique method to produce 3D polymeric structures with sub micro resolution This technique introduced a major breakthrough for manufacturing some products which is really impossible using other methods of additive manufacturing AM approaches such as fused deposition modeling FDM , Stereolithography SLM or selective laser melting SLA We report on 3D micro nano structuring based on 2PP In this work, special two photon initiators 2PIs with high two photon cross section were first synthesized Then their two photon absorption 2PA was determined using normal Z scan technique and a new proposed technique using femtosecond laser pulses and white light supercontinuum 3D polymeric micro nano structures were produced based on 2PP using a 3D translation stage equipped with a pair of galvo scanner mirrors Femtosecond laser beam containing 150 fs femtosecond pulses were focused using a high numerical aperture objective Different pulse energy and different scanning speed were examined to find out the optimal parameters
