For measurements we have a large-frame Ar laser, a CW mode-locked Ti:Sapphire laser, a frequency doubler and a pulse-picker system. This set-up delivers pulses of 80 fs or 2 ps width, tuneable over the ranges 700-1000 and 350-500 nm, with a mean power of 2 W or 400 mW, a repetition rate of 82 MHz which can be reduced down to some Hz. A streak-camera attached to spectrometer (0.2m) with three gratings is directly interfaced to a computer for the recording of two dimensional (time and wavelength) luminescence maps. The time resolution of the system is 15 ps, which by deconvolution techniques can be reduced to 5 ps. The measurement time window is variable from ns to ms. This laboratory is also equipped with various cryostats and facilities to perform non-linear optical measurements (lamps, photodiodes, etc.)
