Abstract
Glass welding by ultra-short pulsed laser pulses is a complex and highly dynamic process that is influenced by many parameters such as pulse repetition rate, feed speed, pulse duration or laser wavelength. Despite the complexity the understanding of the underlying processes has progressed far enough to support first industrial applications. However, the understanding of the underlying processes is still far from complete. Thus, in the present work we strive to close the knowledge gap regarding the wavelength influence of the ultra-short pulsed laser on the welding. We present an experimental comparison of glass welding by ultra-short pulses at 532 nm and 1064 nm for a range of different irradiation parameters such as pulse energy, pulse repetition rate and feed speed at a full-width-at-half pulse duration of 12 ps for D263 borosilicate glass. The results show smaller crack tendency for the 1064 nm wavelength.
