摘要

Maximization of scan speed and throughput while maintaining resolution is critical for commercialization of two-photon microfabrication technology. We report contrast curves for cationic and free radical two-photon polymerization. An unusual relationship between voxel shape and dose is observed where the voxel ranges from highly asymmetric (aspect ratio of 4:1 or greater) at high dose to nearly spherical at low dose (aspect ratio 1:1 or lower). Similar behavior is observed for both types of polymerization systems suggesting that the change in aspect ratio is not a function of the specific type of chemistry. Qualitative agreement at low dose is found with a simple optical model describing the aspect ratio of intensity contours of a Gaussian beam near the focal point.
