Abstract

Abstract In a cw differential absorption experiment, we examined infrared transitions of excitons in Cu 2O. We find a clear transition which is assigned to induced 1s para → 2p para absorption. Line shape and intensity of induced absorption are analysed as a function of temperature and excitation conditions.
