JILA researchers are using a laser frequency comb -- a technique for making extraordinarily precise measurements of frequency -- to identify specific molecules in gases. The project is helping ...

Researchers at NIST have upgraded their laser frequency-comb instrument to simultaneously measure three airborne greenhouse gases -- nitrous oxide, carbon dioxide and water vapor -- plus the major air ...
