Making a femtosecond laser out of glass

Is it possible to make a femtosecond laser entirely out of 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 ...

Researchers make biodegradable optical components from crab shells

Researchers have developed a process to turn crab shells into a bioplastic that can be used to make optical components known as diffraction gratings. The resulting lightweight, inexpensive gratings are biodegradable and could ...

Maintaining the structure of gold and silver in alloys

EPFL engineers have developed a low-temperature annealing method that maintains the structure of gold and silver when the two metals are combined in an alloy. Their discovery will prove useful in the manufacture of contact ...
