Due to its various possibilities in the study of chemical and biological reactions with only few consumables, the microfluidics field is expanding significantly. To respond to the growing request of industries and universities, we have developed a flexible and various technology to engrave, assemble and seal the microfluidics chips, for prototypes or mass production.

In order to improve the competitiveness of our solution for industrial production purpose, LASEA has focused in particular its work on the improvement of the welding’s speed. In this work, we present a comparison on various parameters between welding of polymerics chips with a gaussian beam profile and a top-hat beam profile. To achieve a top-hat profile beam, we used the Canunda-Pulse solutions from Cailabs for manipulating high-power femtosecond lasers. Canunda-Pulse is a fully reflective passive optical module based on the Multi-Plane Light Conversion (MPLC) technology.
