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 22.9 MPa, which is approximately 22% greater than that of a sample prepared by conventional irradiation by a single-pulse train.
通过超快激光脉冲双脉冲串辐照实现了玻璃衬底的高效微焊接。双脉冲辐照等时间光束整形技术为高质量、高效率的材料加工提供了更大的灵活性。通过双脉冲辐照焊接的两块光致形状玻璃衬底的结合强度评估为 22.9 MPa，比通过单脉冲串常规辐照制备的样品提高了约 22%。
