Abstract

The garnets with disordered structure such as calcium niobium gallium garnet (CNGG) doped with Nd³⁺ are interesting materials for diode pumping. Spectroscopic investigations on Nd³⁺:CNGG have revealed a multisite structure and this is reflected in laser emission characteristics. The purpose of this paper is to present several new spectral aspects, a modeling for the main nonequivalent centers, energy transfer characteristics and an attempt to connect the laser characteristics to centers structure. Samples were grown by Czochralski method with Nd³⁺ from 0.1 to 5 at.% and the high resolution spectral and decay measurements were performed at 10 K. Similar considerations were made in the case of Nd³⁺ doped in calcium lithium niobium gallium garnet (CLNGG).
