Hamm, P.; Wiedmann, S.; Zurek, M. and Zinth, Wolfgang (15. October 1994): Highly sensitive multichannel spectrometer for subpicosecond spectroscopy in the midinfrared. In: Optics Letters, Vol. 19, No. 20: pp. 1642-1644 [PDF, 460kB]


A spectrometer system is presented for time-resolved probing in the midinfrared between 5 and 11 /tLmw ith a temporal resolution of better than 400 fs. Multichannel detection with HgCdTe detector arrays consisting of ten elements in combination with a high repetition rate permits one to record weak absorbance changes with an accuracy of 0.1 mOD.
