Ultra-Fast Laser Fuses Metal Alloys to Glass

Wednesday, May 22, 2019
 

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.

Researchers claim that the new process is transformative for manufacturing, and has direct applications in the aerospace, defense, optical-technology and healthcare sectors. No word yet on a timeline for commercialization.
