(Phys.org)—A team of researchers at Princeton University has found a way to cause any atom to mimic the light emissions of any other atom. In their paper published in the journal Physical Review Letters, the team reveals ...
When you heat a tiny droplet of liquid tin with a laser, plasma forms on the surface of the droplet and produces extreme ultraviolet (EUV) light, which has a higher frequency and greater energy than normal ultraviolet.
