Femtosecond

Turning tellurite glass into a ‘transparent’ light-energy harvester by etching semiconducting patterns using femtosecond laser light. Credit: EPFL / Lisa AckermannResearchers found that exposing tellurite glass to femtosecond laser light creates semiconducting nanocrystals, opening the possibility of turning glass into electricity-generating surfaces using only light.What happens when you expose tellurite glass to femtosecond laser light? That’s the question that Gözden Torun at the Galatea Lab, in a collaboration with…

Scientists have created a compact femtosecond laser from glass, revolutionizing the alignment process and promising advancements in quantum optics and technology miniaturization. This innovative approach, funded by the European Research Council, is poised for commercialization. Credit: Jamani Caillet / EPFLIs it possible to create a femtosecond laser entirely from glass? That’s the rabbit hole that Yves Bellouard, head of EPFL’s Galatea Laboratory, went down after years of spending hours – and hours – aligning femtosecond…
