Application
High-resolution ultrafast measurement, out of the optics lab
A pump pulse excites the sample and a time-delayed probe pulse measures the response, producing a high-resolution temporal record of dynamic phenomena. Traditional setups need a mechanical delay line, which makes them bulky, slow and sensitive to error.
What the dual-comb approach changes
- Optical delay sweeps without moving parts — fast scanning over extended delays.
- Femtosecond-level timing precision from shared-cavity noise correlation.
- Dramatically simpler, smaller systems with no mechanical delay stage.
- Ultra-low relative intensity noise for sensitive measurement at high frequencies.
