Improving Microfluidic Channel Surface Roughness
Microfluidic channel surface roughness might be a concern in direct femtosecond laser ablation, normally yielding an RMS value in the range of a few µm. One solution to improve this value is using the fs bi-burst regime. In an article, entitled “Fabrication of Microfluidic Tesla Valve Employing Femtosecond Bursts,” it is shown how fs-burst mode ablation … Continue reading
