Congratulations to Zheng Wei!

Zheng has successfully defended his thesis in the group of Prof. Ferenc Krausz. 

We are happy to share that Zheng Wei has successfully defended his PhD thesis titled “Field-Resolved Infrared Differential Molecular Fingerprinting” in the group of Prof. Ferenc Krausz. His thesis highlights differential molecular fingerprinting (dMF) as an interferometric strategy within field-resolved infrared spectroscopy. 

Field-resolved infrared spectroscopy probes time-domain molecular vibrational responses that are specific to chemical structure and conformation. In applications such as human plasma analysis, it can provide valuable insights into health and disease. In practice, however, the weak signals of target molecules are often obscured by the intense excitation pulse and the overwhelming response of highly abundant non-signal molecules. 

To overcome this limitation, Zheng’s thesis introduces the approach of differential molecular fingerprinting (dMF), an interferometric strategy integrated into field-resolved infrared spectroscopy. By implying a broadband achromatic interferometer, this approach suppresses the background from the excitation pulse and highly abundant molecules - allowing to observe weak molecular vibrational responses at earlier times. 

Congratulations to Zheng, we wish you all the best for the future!
