Incoherent Beam Superposition and Stacking,ity. According to the ISO-standard [.] this property can be characterized by the beam-parameter product (Q or BPP), multiplying the waist radius (. .) and the far-field divergence (. .) of the beam. In the best case, i.e., without any aberrations, this beam-parameter product remains constant, if the

Laser Systems Beam Characteristics, Metrology, and Standards,me of the laser device is another key aspect. The aim of laser metrology is to obtain reliable information about the laser device and its output. Standard measurement procedures are needed for the comparison of different lasers. It is desirable to compress the information about a laser to a few figu

Applications, main principle of all laser-supported joining technologies is the absorption of laser radiation near to the contact area of the joining partners and — if used — also at the filler material, the transformation of the radiation energy into heat and the transition of part of the irradiated material in
