Development of two-color laser sources for sum-frequency generation spectroscopy

Project: PHD

Description

Development of picosecond OPO pumped synchronously for two-color SFG measurements. This tabletop set-up generates two beams tunable in the visible (410-710 nm) and infrared (2.5-20 µm) spectral ranges. It allows the study of electron-phonon couplings at interfaces. In particular, the KTP/CdSe OPO extends SFG spectroscopy to the 10 to 20 µm spectral range.
