Laser processing

Ultrashort-pulse laser processing has grown into a key technology underpinning next-generation manufacturing, yet the understanding of its underlying processes remains insufficient, and processing still relies heavily on empirical optimization. In this talk, toward precise measurement and modeling that make processing predictable, I present our efforts including direct measurement of the focal beam profile and the fluence-mapping method, simulation of nonlinear pulse propagation in air, and time-resolved measurement of laser-induced plasma. I further discuss our latest attempts to capture laser processing in situ within dielectrics, along with future prospects.
