Description
The HARPIA ultrafast spectroscopy system is a modular platform designed for advanced time-resolved spectroscopic measurements. The system is centered around the HARPIA-TA transient absorption spectrometer, which enables pump-probe experiments with high temporal resolution. HARPIA supports multiple measurement modules including fluorescence upconversion, Kerr gate spectroscopy, TCSPC, and multi-pulse experiments. The modular design allows seamless switching between measurement modes while maintaining high optical stability through a compact monolithic optical layout.
