Abstract
Effective energy windows for two-photon absorption (TPA) photopolymerizatio n of resins were investigated and, with a properly selected laser pulse ene rgy, exquisite three-dimensional (3D) microstructures with submicrometer sp atial resolution were achieved. The results show the inherent utility of TP A in the fabrication of real 3D patterns. In particular, we propose and uti lize a resin pre-exposure technique by which freely movable components affi xed to an axle are built, demonstrating a new application of TPA in laser m icrofabrication.
