It was the summer of 1969. Scientists in Rochester, N.Y., prepared to fire up an experimental laser. Everything was in place—from the cooling system to ensure the laser didn't burst into flames to the ...
In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...
Scientists show that it is possible to make a femtosecond laser that fits in the palm of one's hand using a glass substrate. Is it possible to make a femtosecond laser entirely out of glass? That's ...
At the heart of our sun, fusion is unfolding. As hydrogen atoms merge to form helium, they emit energy, producing the heat ...

Laser sculpting gives rare control over particle acceleration
Physicists are learning to carve laser beams into intricate shapes that can grab hold of electrons and push them with a ...
New research revealed a worrying weakness of self-driving vehicles, as a basic laser toy can make such a car completely blind. The study was conducted by researchers at the University of Michigan, the ...
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 – ...
