The formation of individual molten volumesin regular intervals was achieved by means of power modulation, resultingin a predictable and reproducible weld seam with a regular structure. Atconstant average power, a homogeneous weld seam without a periodicsignature was alternatively achieved by means of a shaped beam generatingan elongated interaction volume and resulting in a continuous melting ofthe material. The influence of the two approaches, and their combination onthe process dynamics, was analyzed by means of high-speed videos of theplasma emission and of the formation of the seams.Reproducible process regimes during glass welding by bursts ofsubpicosecond laser pulseshttps://puma.ub.uni-stuttgart.de/bibtex/24abd23e6387c1f5570df2862bbfe34ea/ifswifsw2020-12-17T08:05:08+01:00laser_weldingsend:unibiblio myown welding glass laser peer from:thomas_graf <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Sebastian Hecker" itemprop="url" href="/person/13d95033c18310f9c7a583fdaa3d45b72/author/0"><span itemprop="name">S.
