Tailored beam shaping to improve microfluidics chips welding with ultra-short pulse laser

The microfluidics field, due to its various possibilities in the study of chemical and biological reactions with only few consumables, is expanding significantly. A flexible solution has been developed based on Ultra-Short Pulsed laser technology to engrave different microfluidic channels on a chip, and to seal them. We describe here a solution to improve the welding’s speed and quality based on a tailored beam shaping with Multi-Plane Light Conversion (MPLC) technology. The fully reflective module is used with a high-power femtosecond laser. The optical performance of the module and achieved improvement on the welding are detailed.
