A phosphate-based laser glass with various concentrations of Nd 3+ ions has been synthesized, the composition of which provides enhanced melting properties and the possibility of obtaining optically homogeneous glass in small-volume crucibles. The set of the main spectral-luminescence characteristics of the obtained glasses is determined and it is shown that this matrix provides a long luminescence duration and a high quantum yield in a wide range of Nd 3+ concentrations. Taking into account good cooking and working properties, this matrix composition seems to be useful in the development of new laser materials with a modified luminescence band due to activation by various rare-earth elements and modification of the matrix with highly polarizable cations.
