We report for the first time laser action in resonantly-pumped transparent polycrystalline Er:YAG ceramic developed through a 2-step approach combining spark plasma sintering and HIP post treatment. Microstructural and spectroscopic properties, as well as the laser performance of large scale 0.5at.% Er:YAG transparent polycrystalline ceramic are discussed. A maximum slope efficiency of ∼31% and optical-optical efficiency of 20% was measured.
我们首次报道了通过火花等离子烧结和热等静压后处理相结合的两步法制备的共振泵浦透明多晶Er:YAG陶瓷中的激光作用。讨论了大规模0.5at.% Er:YAG透明多晶陶瓷的微观结构和光谱特性以及激光性能。测量得到的最大斜率效率约为31%，光光效率为20%。
