Femtosecond Frequency Combs with Few‐kHz Passive Stability over an Ultrabroadband Spectral Range
Laser &Photonics Reviews, Volume 17, Issue 7, July 2023., 2023 The noise properties of fiber‐based frequency combs are studied in a wide parameter range. In specific regions, the free‐running linewidth of the carrier‐envelope offset frequency drops below 1 kHz. All relevant contributions to the phase noise and their interplay are identified.
