摘要

与传统的微加工技术相比,双光子聚合技术由于其具有构建任意、复杂和超精密的三维(3D)微结构的能力而引起了人们的极大兴趣。该工艺利用飞秒激光脉冲和光刻胶,光刻胶在激光波长(515 nm)处是透明的,但会吸收高强度的两个光子进行聚合,从而有可能制造用于先进光子学和生物医学应用的设备。本文讨论了双光子聚合法制备三维微结构的方法。

3D Printing by Two-Photon Polymerization
Compared with conventional microfabrication techniques, two-photon polymerization has attracted significant interest due to its capability of building arbitrary, complex and ultraprecise three-dimensional (3D) microstructures with sub-100 nm resolution. The process exploits femtosecond laser pulses and a photo resist that is transparent at the laser wavelength (515 nm) but absorbs two photons at high intensity to polymerize, resulting in the possibility of fabricating devices for advanced photonics and biomedical applications. In this paper, the manufacturing of 3D microstructures through two-photon polymerization is discussed.
