Transient absorption spectrometer Harpia is an instrument for measuring femtosecond transient absorption spectra and kinetics. The instrument is designed to be used with multi-kHz repetition rate Yb:KGW femtosecond laser systems (Pharos, Carbide), but can also be used with 1 kHz Ti:Sapphire lasers. Harpia includes entire optical setup with all-reflective white light supercontinuum probe line and ...
