Abstract

Efficient microwelding of glass substrates by irradiation by a double-pulse train of ultrafast laser pulses is demonstrated. Temporal beam shaping techniques such as double-pulse irradiation enabled increased flexibility for high-quality, high-efficiency material processing. The bonding strength of two photostructurable glass substrates welded by double-pulse irradiation was evaluated to be 22.9MPa, which is approximately 22% greater than that of a sample prepared by conventional irradiation by a single-pulse train.
