Comparative spectroscopic investigation of Yb-doped YAG, YSAG and YLaO₃ transparent ceramics

Transparent Yb doped YAG, YSAG and YaLaO₃ ceramics are fabricated by using the co-precipitation method. The spectral properties and thermal parameters of these Yb doped cubic phase transparent ceramics are compared, and their different and potential applications are also analysed. The absorption cross-section and the emission cross-section of these ceramics are measured and calculated. The essential properties of these materials especially for the rep-rated pulsed high-energy diode-pumped solid-state lasers are investigated. The results show that Yb doped YAG, YSAG and YaLaO_3 are all suitable materials used for diode-pumped solid-state lasers.
