Specific absorption losses in five samples of Nd : YAG (1% – 4%) optical ceramics are measured by laser calorimetry. The measurement results show that the specific losses increase from 7 × 10-3 to 13 × 10-3 cm-1 as the neodymium concentration increases above 2 at %. The principal possibility of separate determination of scattering and absorption losses using additional measurements of total losses in ceramic material is shown.
