Investigations on laser-welding
IEEE Journal of Quantum Electronics, 1975A welding method has been developed that makes use of fundamental mode laser pulses. These pulses show single-mode relaxation oscillations with a high peak power first spike causing breakdown of the material surface. The laser emission following the first spike can be adapted to the welding requirements and the material properties.

Surface tension stabilized laser welding (donut laser welding)—A new laser welding technique
Journal of Laser Applications, 2013A new laser welding process is presented which delivers a porosity free, spatter free weld. The process involves a donut shaped melt with a central hole of the same order of magnitude as the material thickness. The laser illuminates only the leading section of this melt. The hole is kept open by the melt surface tension.
