A method for the laser-induced joining of a first, vitreous joining partner with a second joining partner using ultrashort laser pulses, comprising the following method steps: - positioning the two joining partners (5, 6) with a gap, caused by the surface roughness of the joining partners (5, 6), between their surfaces (7, 8) to be joined in a joining plane, - radiating a focused processing beam (2, 14) of an ultrashort pulse laser (1, 16) into the vitreous joining partner with the focus near the joining plane while forming a melt zone and a low-viscosity zone surrounding same around the focus of the processing beam (2, 14) in the vitreous joining partner due to laser-induced ionization effects such that the spatial expansion of the low-viscosity zone extends to the surface of the vitreous joining partner due to heat conduction, and the thermal expansion of the melt zone causes the surface of the vitreous joining partner to bulge in the region of the focus (9, 17) of the processing beam (2, 14) while reducing the gap towards the second joining partner to a dimension for achieving an optical contact of the joining partners (5, 6) in a joining zone formed thereby, and - adhering the joining partners (5, 6) in the joining zone due to the Van der Waals forces acting between the joining partners (5, 6) in the region of the joining zone, characterized in that - a focused ultrashort-pulse laser beam (2, 14) is radiated into the melt zone, the irradiation parameters of which are selected such that gas bubbles are additionally generated in the melt zone due to the laser-induced ionization effects generating the melt zone, the increase in volume of which supports the bulging of the surface of the vitreous joining partner and the associated reduction of the gap between the joining partners (5, 6), and - gas bubbles generated by the focused ultrashort-pulse laser beam (2, 14) in the vitreous joining partner are transported into the melt zone by an advancing movement of the focus (9, 17) of the ultrashort-pulse laser beam (2, 14) within the vitreous joining partner with the aid of a laser-based entrainment effect caused by the surface tension of the gas bubble. - positioning the two joining partners (5, 6) with a gap, caused by the surface roughness of the joining partners (5, 6), between their surfaces (7, 8) to be joined in a joining plane, - radiating a focused processing beam (2, 14) of an ultrashort pulse laser (1, 16) into the vitreous joining partner with the focus near the joining plane while forming a melt zone and a low-viscosity zone surrounding same around the focus of the processing beam (2, 14) in the vitreous joining partner due to laser-induced ionization effects such that the spatial expansion of the low-viscosity zone extends to the surface of the vitreous joining partner due to heat conduction, and the thermal expansion of the melt zone causes the surface of the vitreous joining partner to bulge in the region of the focus (9, 17) of the processing beam (2, 14) while reducing the gap towards the second joining partner to a dimension for achieving an optical contact of the joining partners (5, 6) in a joining zone formed thereby, and - adhering the joining partners (5, 6) in the joining zone due to the Van der Waals forces acting between the joining partners (5, 6) in the region of the joining zone, - a focused ultrashort-pulse laser beam (2, 14) is radiated into the melt zone, the irradiation parameters of which are selected such that gas bubbles are additionally generated in the melt zone due to the laser-induced ionization effects generating the melt zone, the increase in volume of which supports the bulging of the surface of the vitreous joining partner and the associated reduction of the gap between the joining partners (5, 6), and - gas bubbles generated by the focused ultrashort-pulse laser beam (2, 14) in the vitreous joining partner are transported into the melt zone by an advancing movement of the focus (9, 17) of the ultrashort-pulse laser beam (2, 14) within the vitreous joining partner with the aid of a laser-based entrainment effect caused by the surface tension of the gas bubble.
