Here are some research results which I did while I was at National Tsing-Hua University (Taiwan) and Caltech (USA).
Most sensitive spectroscopy 👑
Most sensitive spectroscopy 👑
Since an optical cavity with high finesse can provide over 10^6 times of original path-length and incident optical power, cavity-enhanced laser spectroscopy have been widely used as a detection method for highly sensitive detection in fundamental physics and applied science.
FMS: Frequency Modulation Spectroscopy, OF-CEAS: Optical–Feedback Cavity Enhanced Absorption Spectroscopy, D(CEAS): Direct Cavity Enhanced Absorption Spectroscopy, NICE-OHMS: Noise-Immune Cavity-Enhanced Optical-Heterodyne Molecular Spectroscopy
🍻 we got the signal from Single Aerosol! HOREY!

Time-Resolved Extinction Measurements of Aerosols in the Single-Particle Regime.
The cavity ring down time decreases because the cavity experiences the loss when a single aerosol passes through the interaction area.
