AI Insight

This study demonstrates a two-step fabrication method for high-quality fused silica micro-lenses that combines femtosecond laser-induced chemical etching with atmospheric pressure plasma post-processing using inert gases. The plasma treatment significantly improved the optical surface quality of the micro-lenses by reducing surface roughness and removing micro-defects created during the initial laser etching process. The researchers achieved smooth, high-precision micro-optical components with enhanced optical performance suitable for integration into miniaturized optical systems.


This advancement enables more cost-effective and precise manufacturing of micro-optical components for applications in telecommunications, medical imaging devices, and miniaturized sensor systems. The atmospheric pressure plasma method offers a practical alternative to vacuum-based techniques, potentially making high-quality micro-optics more accessible for industrial production.
