Physicists confirm surprisingly small proton radius

International team of physicists confirms surprisingly small proton radius with laser spectroscopy of exotic hydrogen. The initial results puzzled the world three years ago: the size of the proton (to be precise, its charge ...

Speedy terahertz-based system could detect explosives

Terahertz spectroscopy, which uses the band of electromagnetic radiation between microwaves and infrared light, is a promising security technology because it can extract the spectroscopic "fingerprints" of a wide range of ...

New VECSEL could mean a step forward for spectroscopy

(PhysOrg.com) -- "Unfortunately, for spectroscopy, the beam quality of quantum cascade lasers is not satisfying," Hans Zogg tells PhysOrg.com. "We are developing lasers for the mid-infrared range which have an especially ...
