Laser drilling, cutting, and scribing with non-diffracting laser beams
Applying non-diffracting laser technology for precise and high-speed drilling, cutting, and scribing applications.
Project Overview
This project focuses on enhancing laser-based material processing using non-diffracting beams such as Bessel and Airy beams. These beam profiles maintain their intensity over extended propagation distances, enabling precise drilling, cutting, and scribing with minimal thermal damage and superior edge quality.
QuantLight’s approach leverages structured beam shaping to deliver high aspect ratio holes, ultra-thin cuts, and micro-scale scribing patterns in metals, semiconductors, and transparent materials—ideal for electronics, photonics, and biomedical device fabrication.
Challenges & Constraints
Traditional Gaussian beams suffer from diffraction and energy spread, limiting depth control and edge precision. Generating stable non-diffracting beams requires advanced optics and alignment, while managing heat accumulation and debris removal remains a constraint in high-repetition-rate systems.
Beam Shaping Technology
Custom diffractive optics generate Bessel and Airy beams for extended depth of focus and minimal diffraction.
Precision Material Interaction
Enables high-aspect drilling, fine scribing, and clean cuts with reduced heat-affected zones and debris.
Multi-Material Compatibility
Effective on metals, semiconductors, polymers, and transparent substrates used in microelectronics and photonics.
Project Solution
QuantLight developed a modular laser processing system integrating non-diffracting beam generation, adaptive optics, and real-time monitoring. The platform supports programmable drilling, cutting, and scribing workflows with micron-level precision and repeatability.
Final Result
The final system delivers high-speed, high-precision laser processing with minimal thermal impact and superior structural integrity. QuantLight’s technology is now deployed in advanced manufacturing lines for electronics, photonics, and biomedical devices.
