摘要
The influence of the duration of melting, the purity of the reagents used for synthesis, and the material of crucibles on the optical losses in laser neodymium high-strength aluminoborophosphate glass has been investigated. The obtained results have demonstrated that the main reason of emerging of optical losses at the lasing wavelength in the glass under study is the interaction of the crucible material with the aluminoborophosphate melt which is aggressive at a synthesis temperature of 1350掳C.
