Ultrafast GHz burst laser processing has emerged as a powerful and versatile technique for high-precision material modification, offering unique advantages in terms of reduced thermal damage, enhanced ablation efficiency, and superior surface quality. This abstract presents its application across three distinct domains to highlight the versatility of this manufacturing approach.

First, in the engraving and polishing of steel molds for microfluidic applications, GHz burst regimes enable smooth surface finishes and high-resolution engraving by combining efficient material removal with a final polishing step. This is particularly beneficial for polymer replication processes, where mold quality directly impacts device performance.

Second, in microelectronics, the generation of Through-Glass Vias (TGVs) using ultrafast GHz lasers provides a reliable method for creating high-aspect-ratio, crack-free vias in brittle substrates such as glass. The burst mode enhances energy deposition control, enabling precise drilling with reduced microcracking and improved sidewall quality compared to conventional approaches. These features are critical for advanced packaging and 3D integration technologies.

Finally, the integration of GHz burst laser systems with robotic platforms and fiber-based beam delivery opens new possibilities for flexible and scalable industrial applications. Fiber transport enables stable beam guidance, while robotic handling allows processing of complex 3D geometries and large-area components. Together, these capabilities support automation and adaptability in manufacturing environments, extending ultrafast laser processing beyond laboratory settings into high-throughput production.

Overall, GHz burst ultrafast laser processing represents a transformative tool across several application domains and opens up new horizons for advanced manufacturing.
