Nano-, pico-and femtosecond laser machining of bioabsorbable polymers and biomedical composites

In this work, bioabsorbable polymers and biomedical composites were machined with three different lasers. Laser micromachining of grooves were studied using nanosecond, picosecond, and femtosecond lasers. Profile measurements, topography, surface roughness, microstructure and quality of the samples were studied.In this work, bioabsorbable polymers and biomedical composites were machined with three different lasers.
