Here we measure the luminescence, reflectivity, absorption and excitation of the luminescence in the visible and near infrared. It is equipped with various excitation sources (Ar Ion laser UV extended and 1000 W monochromatized-Xe lamp); a 0.5 m single and a 0.75 m double spectrometers; a cooled GaAs and InGaAs photomultipliers for photon-counting, a cooled Ge avalanche photodiode with lock-in and chopper, and an optical multichannel array (EG&G OMA); various cryostats (LN, He flux, He bath with or without magnetic fields). A computer controlled VSL system is available for routine measurements of optical gain. All the measurements are controlled by computers.
