研究了用提拉法生长的无序类白钨矿双掺杂Yb：NaGd（MoO 4）2和Yb：NaLa（MoO 4）2晶体的吸收光谱、荧光光谱和荧光衰减动力学。测量了Yb ~（3+）离子2F ~（7/2）Participate ~ 2F ~（5/2）跃迁的吸收截面和荧光截面，计算了激光介质的增益谱。讨论了所研究晶体作为固体激光器工作介质的应用前景。
The absorption and fluorescence spectra, as well as fluorescence decay kinetics of Yb3+ion in disordered scheelite-like double molybdates Yb:NaGd(MoO4)2and Yb:NaLa(MoO4)2, grown by Czochralski, have been investigated. The absorption and fluorescence cross-sections of the transitions2F7/2↔2F5/2of Yb3+ion in these crystals have been determined, gain spectra of laser medium have been calculated. Prospects of the application of investigated crystals as active media of solid-state lasers are discussed.
