Abstract
Nd-doped disordered garnet crystal CNGG (CaNbGa garnet1 is attractive for laser diode pumping because of nonuniform broadening of absorption spectra and its higher-than-glass thermal conductivity. The disordered structure of CNGG crystal is the result of random distribution of the niobium and gallium ions and vacancies at octahedral and tetrahedral lattice sites. Besides, it can be grown at low temperature (melting point 1430°C) by using a platinum crucible.
