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 croes-section of these ceramics are measured and calculated.The essential properties of these materials especially for the rep-rated pulsed high-enerKy diode-pumped solid-state lasers are investigated.The results show that Yb doped YAG,YSAG and YaLaO3 are all suitable materials used for diode-pumped solid-state lasers.
