摘　　要：采用中频感应提拉法成功生长出Yb(15 at%),Ho(1 at%)∶YAG激光晶体,研究了室温下晶体的吸收光谱,发射光谱特性和荧光寿命。吸收光谱中在938 nm处存在Yb3+的吸收带,能与InGaAs激光二极管(LD)有效耦合,适合激光管二极抽运。荧光光谱中存在两个荧光主峰,分别位于1907 nm和2091 nm附近。研究表明:Yb,Ho∶YAG晶体是一种有发展前景的激光增益介质。The laser crystal Yb（15 at%）,Ho（1 at%）∶YAG was grown using medium frequency induction heating by Czochralski method.The features of absorption,emission spectra and fluorescence lifetime of Yb,Ho∶YAG crystal at room temperature were studied.The absorption band is centered at 938 nm of Yb^3＋,which are suitable for InGaAs diode laser pumping.There are two main peaks at 1907 nm and 2091 nm in the fluorescence spectrum.The results indicate that Yb,Ho∶YAG is a promising laser material for high power laser output.
