Precise Molecular Spectroscopy and Frequency Metrology with Frequency Combs
Optical frequency combs have transformed optical metrology by establishing a direct, phase-coherent link between radio and optical frequencies. This lecture explores how these "optical rulers" enable unprecedented precision in molecular spectroscopy. I will cover the core principles of comb generation, stabilization, and direct frequency comb spectroscopy (DFCS), highlighting techniques like dual-comb spectroscopy for rapid, high-resolution broadband measurements. Attendees will learn how comb-based techniques probe fundamental molecular dynamics, enhance gas-sensing sensitivity, and advance optical atomic clocks. Ultimately, this session bridges foundational laser physics with cutting-edge metrology and emerging real-world chemical applications.
