Spectral Peaked Optical Frequency Comb for Highly Sensitive Spectroscopy

Advanced Photonics Research
Optical frequency combs represent a breakthrough in the field of metrology. Because an optical frequency comb has a large number of comb modes, the optical energy is dispersed over the comb modes, and the optical energy per comb mode is very small.

Raman-Kerr comb generation based on parametric wave mixing in strongly driven Raman molecular gas medium

Physical Review Research, 2020
We report on experimental and theoretical demonstrations of an optical comb spectrum based on a combination of cascaded stimulated Raman scattering and four-wave mixing mediated by Raman-induced nonresonant Kerr-type nonlinearity.
