Cr与RE（Tm,Er,Ho）共掺的YAG单晶光纤的生长

Growth of Cr and RE(Tm, Er, Ho )Codoped YAG SCF

摘要:

探讨了用激光加热基座（ＬＨＰＧ）法生长ＲＥ（Ｔｍ，Ｈｏ，Ｅｒ）：ＹＡＧ和（Ｃｒ，ＲＥ）：ＹＡＧ优质单晶光纤（ＳＣＦ）的工艺，测定了光纤的吸收谱和荧光谱。结果表明，以经粉末压制、焙烧并经ＬＨＰＧ法快速（３—６ｍｍ／ｍｉｎ）生长成的２ｍｍ多晶圆棒为源棒，在合适的拉速（小于以单晶棒为源棒的拉速）下，可以生长出优质的单晶光纤。其光学性能与大块晶体相同。

Abstract:

A laser heating pedestal growth technique has been used to grow.Single Crystal Fibers (SCF) made from RE: YAG and (Cr,RE): YAG .The technology growing the SCF qualified for good character is discussed. A simpie method of prepering source rods from powders to feed growth of the SCF is described.The absorption and fluorescence spectra of SCF have been measured.
