Abstract
Disclosed are a system and method for micro-nano machining by femtosecond laser two-photon polymerization. The system includes: a femtosecond laser, an external light path modulation unit, an image capture apparatus, a focusing lens, a displacement platform, a computer and a monitoring apparatus, where the image capture apparatus is configured to capture cross-section graphs of a three-dimensional micro-nano device layer by layer, so that modulated femtosecond lasers form parallel beams arranged according to all layers of the cross-section graphs.
