Aim: To explore Diffractive Optical Element (DOE) technology for multi-beam splitting to enhance the productivity and efficiency of femtosecond laser micro-drilling.
Brief description: The MultiBEAM project focuses on addressing limitations in laser micro-drilling efficiency caused by heat-affected zones (HAZ) when increasing laser power. By implementing DOE technology, the project aims to split the laser beam into multiple beams, maximizing power utilization while maintaining high quality. The approach will be tested on various drilling strategies to evaluate improvements in speed and precision.
Benefits: Adopting multi-beam technology reduces production time and cost per unit, making micro-drilling more accessible for applications like micro-filtering, cell separation in bio-sensors, and optical or deposition masks. This innovation enhances process scalability and supports broader adoption of femtosecond laser drilling for repetitive, high-precision structures.
