This work revisits the excitonic properties of Cu2O as observed with optical techniques, making use of current days experimental capabilities providing very precise measurements, with high energy and/or time resolution, using a variety of high power coherent pulsed light sources, intense magnetic fields, and cryogenic temperatures. A short overview of the theory of excitons and the excitonic Bose-Einstein condensation is presented. We discuss the ideas and results of the experiments aimed at determining the exciton gas parameters and their time evolution. It was shown that the lifetime is one of the most critical parameters determining whether a condensate state may occur. It was concluded, that the lifetime is strongly depends on amount of...
