Ultra-Fast Laser Fuses Metal Alloys to Glass

A new process enabling the welding of metal alloys to glass has been developed by researchers at Heriot-Watt University in Edinburgh, United Kingdom, a development that may provide significant new opportunities for manufacturers, according to researchers.

Using an “ultra-fast” laser, the team successfully welded optical materials such as quartz, borosilicate glass and sapphire to aluminum, titanium and stainless steel. The Heriot-Watt laser system employed in the research provides picosecond-long pulses of infrared light in tracks along the materials to fuse them together.
