Measuring the spectral phase of a pulse is key for performing wavelength resolved ultrafast measurements in the few femtosecond regime. However, accurate measurements in real experimental conditions can be challenging. We show that the reflectivity change induced by coherent phonons in a quantum material can be used to infer the spectral phase of an optical probe pulse with few-femtosecond accuracy.

Deoxynivalenol (DON) is known for its acute and chronic toxicity and is the most common contaminant of cereal grains. Since no legal limits are set for DON in wheat-based products and specific foods intended for children over 3 years on the market, a high risk of overexposure to this contaminant may emerge.

- Atomic-scale defects in crystalline materials like diamond significantly influence their optoelectronic performance, with the NVH defect being a key player for quantum technologies.
- The NVH defect consists of a lattice vacancy involving nitrogen impurities and a hydrogen atom, which leads to distinct absorption features in the mid-infrared range.
- The study employs advanced infrared absorption spectroscopy to investigate the vibrational dynamics of the NVH defect, revealing energy relaxation pathways and enhancing our understanding of atomic-scale defects for future applications.
