Abstract

Femtosecond laser has great advantages in the processing of soft materials due to its extremely short pulse duration and high peak intensity with modest average power, which realizes the fabrication of precise structure without significant thermal modification. Since a number of soft materials including polymers show high transmittance for visible to near-infrared wavelength, three dimensional structures can easily be fabricated via intense nonlinear absorption. In this presentation, we will describe our study on ultrafast laser processing of biomaterials, in terms of both subtractive and additive techniques, toward the bio-compatible devices
