Abstract
Method and system for a laser welding process employing the use of a single pulsed fiber laser source configured to generate a radiative output with a wavelength spectrum extending from about 1.8 microns to about 2.6 microns. In a specific case, the laser output from the single pulsed fiber laser source is focused onto the interface of the two pieces of materials at least one of which includes any of glasses, inorganic crystals, and semiconductors.
