主要内容：

Optical whispering-gallery-mode resonators (WGMRs) have emerged as promising platforms to achieve label-free detection of nanoscale objects and to reach single molecule sensitivity. In the last few years, we have demonstrated very sensitive detection and measurement of nanoparticles using mode splitting, rare-earth-ion doped microcavity lasers and Raman lasers. Notably, we detected and counted individual dielectric nanoparticles down to a record low radius of 10 nm by monitoring a beatnote signal generated when split Raman lasing lines are heterodyne-mixed at a photodetector. In this talk, the fundamentals of WGMRs and their applications will also be briefly covered.
