High density terahertz frequency comb produced by coherent synchrotron radiation
High density terahertz frequency comb produced by coherent synchrotron radiation
Frequency combs (FC) have radically changed the landscape of frequency metrology and high-resolution spectroscopy investigations extending tremendously the achievable resolution while increasing signal to noise ratio. Initially developed in the visible and near-IR spectral regions, the use of FC has been expanded to mid-IR, extreme ultra-violet and X-ray. Significant effort …
