Time-resolved spectroscopy
The setup for femtosecond time-resolved (TR) spectroscopy is mainly intended for time-resolved photoluminescence (PL) spectroscopy and pump-and-probe measurements. For excitation, the whole spectral range from 250 nm up to 1500 nm can be covered. The sample is usually mounted in a liquid helium flow cryostat for temperatures between 5 and 300 K. The emitted PL intensity is collected by standard or microscope optics and dispersed in a 0.22 m single monochromator. For detection, a streak camera with a photocathode for the near-infrared to visible (IR) or visible to ultraviolet (VIS) spectral region can be used in order to simultaneously detect the PL signal time- and spectrally resolved.
