High-aspect-ratio micro-objects were fabricated via multiphoton-absorption photopolymerization using femtosecond lasers. A 100-MHz, 800-nm mode-locked Ti:sapphire laser oscillator was used as the light source. The femtosecond laser pulses were focused by a 0.85 numerical aperture, 60 X objective lens, onto the photoresist. Micro-objects with lateral dimension, 35% the diffraction limit and an aspect ratio close to 4 were produced.
