About the project:
FEMTOWELD is a collaborative project between CELIA research laboratory, AMPLITUDE SYSTEMES and ALPhANOV technology center. The project’s mission is to develop a technological solution for glass welding and cutting based on the use of femtosecond laser pulse (100 to 300 fs) and high average power (up to 100 W).
ALPhANOV aims to produce high-quality cut-by-filamentation at cutting speeds of a few hundreds of mm/s, with chipping at the exit-face of less than 5 µm.
The welding must have a mechanical strength of 90% compared to the raw material with minimum welding speed of 50 mm/s.
Welding and cutting will be performed on several types of glass: soda-lime glass (applications in construction, architecture, flat panel display production and consumer electronics), borosilicate glass (applications in optics and photonics) and sapphire (applications in opto-electronics and watchmaking).
Overall budget: EUR 1 million
