Abstract
The purpose of this work is to increase the power of the lanthanumneodymium-magnesium hexaaluminate "LNA" laser emission. When Ga is substituted for Al the unit cell parameters and consequently the Nd-O distances increase, therefore crystal field experienced by Nd3+ and fluorescence quenching decrease. It is then possible to increase the concentration of the Nd3+ activators ions in the laser crystals. Synthesis, composition domain, optical properties and crystal growth of lanthanum-neodymium aluminogallates with a magnetoplumbite-like structure are described.
