Novel high-power laser modules for drying applications based on VCSEL arrays

We developed a new generation of high-power laser modules for laser drying in battery electrode fabrication. Low power densities and homogeneous heating with full system efficiencies ⪆50% is within the record system efficiencies offered today. Moreover, simple scalability of the illumination profile and highly standardized fabrication techniques are the game changer benefits from using VCSELs as light source.
