 Noise-immune cavity-enhanced optical heterodyne molecular spectroscopy

Noise-immune cavity-enhanced optical heterodyne molecular spectroscopy (NICE-OHMS) is a highly sensitive analytical technique used to detect and characterize molecular species. It combines several advanced concepts from optics and spectroscopy to achieve high sensitivity and selectivity in molecular detection. ### Key Components of NICE-OHMS: 1. **Cavity Enhancement**: NICE-OHMS utilizes an optical cavity to enhance the interaction between light and the molecules being studied.
