Abstract
A spectrometer system is presented for time-resolved probing in the mi dinfrared between 5 and 11 mu m with a temporal resolution of better t han 400 fs. Multichannel detection with HgCdTe detector arrays consist ing of ten elements in combination with a high repetition rate permits one to record weak absorbance changes with an accuracy of 0.1 mOD.
