Abstract

A spectral and dynamic study of spontaneous and stimulated emission of Nd3+ in yttrofluorite CaF2YF3(5%) crystals proves the existence of two main sites for the rare-earth ion in these crystals. Flash-lamp-pumped laser experiments show the existence of two laser output lines, centered at 1054 and 1063 nm, which correspond to stimulated emissions from the two resolved Nd3+ sites. The dependence of the time-resolved laser output energy and relative intensities of both lines on the pump energy suggests the existence of some kind of coupling between the two emissions produced by the stimulated-emission field itself. The ratio between the output energies at the two wavelengths was modeled as a simple rate-equation laser model that takes the stimulated-emission coupling into account.
