Glass welding by ultrashort laser pulses allows joining without the need of an absorber or a preheating and postheating process. However, cracks generated during the welding process substantially impair the joining strength of the welding seams. In this paper a sample preparation method is described that prevents the formation of cracks. The measured joining strength of samples prepared by this method is substantially higher than previously reported values.
通过超短激光脉冲进行玻璃焊接，无需吸收剂或预热及后热过程即可实现连接。然而，焊接过程中产生的裂纹会严重削弱焊缝的连接强度。本文描述了一种防止裂纹形成的样品制备方法。用该方法制备的样品测得的连接强度显著高于先前报道的值。
