Abstract
A method for joining at least two parts by using ultrashort laser pulses of a laser beam of an ultrashort pulse laser is provided. At least one of the two parts to be joined is transparent for a wavelength of the ultrashort laser pulses. The method includes joining the at least two parts by using the ultrashort laser pulses of the laser beam along a joining seam. The joining seam has at least two joining points and a joining gap lying between the at least two joining points. Each joining point is longer than 10 μm.
