Agile spectral tuning of high order harmonics by inteference of two driving pulses
Vittoria Schuster, Vinzenz Hilbert, Robert Klas +2
In this work the experimental realization of a tunable high photon flux extreme ultraviolet light source is presented. This is enabled by high harmonic generation of two temporally…
Ultraviolet Dual Comb Spectroscopy: A Roadmap
Vittoria Schuster, Chang Liu, Robert Klas +4
Dual Comb Spectroscopy proved its versatile capabilities in molecular fingerprinting in different spectral regions, but not yet in the ultraviolet (UV). Unlocking this spectral win…
Coherent Raman spectro-imaging with laser frequency combs
Takuro Ideguchi, Simon Holzner, Birgitta Bernhardt +3
Optical spectroscopy and imaging of microscopic samples have opened up a wide range of applications throughout the physical, chemical, and biological sciences. High chemical specif…
Raman-induced Kerr-effect dual-comb spectroscopy
Takuro Ideguchi, Birgitta Bernhardt, Guy Guelachvili +2
We report on the first demonstration of nonlinear dual-frequency-comb spectroscopy. In multi-heterodyne femtosecond Raman-induced Kerr-effect spectroscopy, the Raman gain resulting…
Cavity-enhanced dual-comb spectroscopy
Birgitta Bernhardt, Akira Ozawa, Patrick Jacquet +7
The sensitivity of molecular fingerprinting is dramatically improved when placing the absorbing sample in a high-finesse optical cavity, thanks to the large increase of the effecti…
