Tiny ring laser accurately detects and counts nanoparticles

(Washington University in St. Louis) A ring-shaped laser no bigger than a pinprick can accurately detect and count individual viruses, the particles that jumpstart cloud formation or those that contaminate the air we breathe. A particle disturbs the light circulating in the ring, splitting the lasing frequency. This split is a measure of the particle's size.
