   en.wikipedia.org/wiki/Soldering

   Laser soldering is a technique where a 30–50 W laser is used to melt and solder an electrical connection joint. Diode laser systems based on semiconductor junctions are used for this purpose. [21] Suzanne Jenniches patented laser soldering in 1980. [22] Wavelengths are typically 808 nm through 980 nm. The beam is delivered via an optical ...

   Laser sintering of gold is a jewellery manufacturing technique [1] first developed by Towe Norlén and Lena Thorsson. [2] Laser sintering [3] of gold starts with gold powder, fine as flour. A laser beam sinters (melts) the gold flour locally in an extremely small point, and any shape may be ‘drawn’ precisely with the laser beam, in three ...
