Ultrashort Pulse Laser Welding Technology Ultrashort-pulse lasers are characterized by extremely high peak power, triggering the nonlinear absorption of transparent materials at the interface and generating localized micro-melt pools that enables effective joining. The welding approach features lower heat input, reduced residual stress, and microscale precision, making it highly promising for welding transparent and brittle materials. This review summarizes recent advances in ultrashort-pulse laser welding technology.
