What happens if femtosecond laser light is shone on tellurite glass? In her thesis work, Gözden Torun of the Galatea Lab collaborated with scientists from Tokyo Tech to address this challenge.
Is 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 lasers for lab experiments. The Galatea laboratory stands at the intersection
Researchers from École polytechnique fédérale de Lausanne (EPFL) display that it is possible to make a femtosecond laser that fits in the palm of one’s hand with the help of a glass substrate.
Miniaturized design could solve alignment challenges for novel optical systems.
Lasers bring technology to artisan watch crystal engraving 26 Jan 2021 EPFL project creates 3D structures within sapphire glass materials. Keep watch: modern tool for artisan work Watch crystals, the clear glass material on the front of any timepiece, have to be tough enough to survive everyday use but also suitable for engraving and customization by the watch manufacturers before the watch is assembled and sold. Historically the preparation of a watch crystal has involved traditional artisan engraving and cutting tools, but a project at Swiss research center EPFL has now applied lasers to...
