Abstract
After selective excitation in either the 2P3/2 or the 4D3/2 multiplet of Nd3+ in YAG or in YAP, the fluorescence properties of these levels are analysed. The YAG:Nd3+ sample exhibits a very strong visible fluorescence attributed to transitions from the 2F(2)5/2 multiplet as a consequence of a very efficient excited state absorption mechanism from the 2P3/2 métastable state.
