Nonradiative relaxation and inhomogeneous splitting of aggregated optical centers in the Nd3`-doped CaF

Abstract

Site-selective #uorescence and laser excitation spectroscopy for di!erent types of optical centers in SrF 2 : Nd3` (0.3 } 1.0%) and SrF 2 : La3` (1.0%) : Nd3` (0.2%) were performed at 4.2 K. The crystal-"eld levels of the 4I 9@2 , 4F 3@2 , and 4G 5@2 multiplets for di!erent Nd3` optical centers were determined in SrF 2 : Nd3` (0.3%). An attempt was made to… (More)
