Creation of ceramic composite active medium YAG:Nd3+/YAG:Sm3+ for the novel high-power near-IR lasers.
popup.description2
The influence of the sintering aids composition on the optimal consolidation temperature of YAG:Nd3+ and YAG:Sm3+ ceramics was investigated. It was found that due to the inhibition of recrystallization during sintering caused by magnesium ions, the microstructure and optical properties of YAG:Nd3+ (Si4++Mg2+) ceramics are significantly less sensitive to the consolidation temperature, compared to YAG:Nd3+ (Si4+), which allows obtaining optical ceramics with low optical losses in a relatively wide temperature range. Using a complex additive, technological routes for obtaining YAG:Nd3+ and YAG:Sm3+ optical ceramics under the same temperature-time conditions of sintering were determined, which will allow manufacturing components for YAG:Nd3+/YAG:Sm3+ composite elements in a common technological cycle, and thus significantly reducing the costs and time of manufacturing such elements.
