Abstract

A spectrometer system is presented for time-resolved probing in the midinfrared between 5 and 11 μm with 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.

Experimental setup. Tunable subpicosecond pulses in the mid-IR are generated by difference-frequency mixing the output of a Ti:sapphire laser regenerative (Reg.) amplifier system with pulses from a traveling-wave dye laser (TWVDL 1) in a AgGaS2 crystal. Excitation pulses at an independent wavelength are generated in a second traveling-wave dye laser (TWDL 2). Broadband transmission spectra of the sample for the IR probing pulses are recorded by spectrograph–MCT-detector combinations.

Each time-resolved spectrum is obtained from a series of ten-channel measurements connected by the solid curves.
