Highly sensitive multichannel spectrometer for subpicosecond spectroscopy in the midinfrared
b'A spectrometer system is presented for time-resolved probing in the midinfrared between 5 and 11 /tLmw ith a\\ntemporal resolution of better than 400 fs. Multichannel detection with HgCdTe detector arrays consisting of\\nten elements in combination with a high repetition rate permits one to record weak absorbance changes with an\\naccuracy of 0.1 mOD.'
