近年来,掺Yb离子的晶体备受关注:掺Yb离子晶体能级结构简单,可以避免激发态再吸收、频率上转换、弛豫振荡和浓度猝灭等效应。此外,掺Yb离子晶体的吸收光谱位于900~1000 nm,无需严格的温度控制即可与InGaAs激光二极管有效耦合,并且具有很宽范围的荧光发射谱,因此这种晶体很有潜
In recent years, Yb ion-doped crystals have drawn much attention: Yb-doped crystal crystals have simple energy level structures and can avoid the effects of excited state reabsorption, frequency upconversion, relaxation oscillation and concentration quenching. In addition, the absorption spectra of Yb-doped crystals lie in the range of 900-1000 nm and can be effectively coupled with InGaAs laser diodes without strict temperature control and have a wide range of fluorescence emission spectra. Therefore, this crystal is very latent
