Optical transitions and absorption intensities of Dy3+ (4f9) in YSGG laser host

Optical spectroscopy of NaLa(WO4)2:Dy3+ single crystal

“…In Table 4, the values of the intensity parameters are compared with those of some popular laser materials doped with Dy 3+ ions. The spectroscopic quality factor [24], X = Ω 4 /Ω 6 , for the Dy 3+ in NaLa(WO 4 ) 2 is determined to be 1.55, which falls within the range of 0.42-1.92 for Dy 3+ doped in different hosts reported by several authors [2,[25][26][27][28]. The relatively high value of X suggests that NaLa(WO 4 ) 2 :Dy 3+ crystal is a potential material for efficient laser action.…”

Visible luminescence characteristics of Dy3+-doped LBTAF glasses

“…Dy 3+ ion-doped glass hosts having the range of spectroscopic quality factors 0.42-1.92 are the good candidates for laser active media [28]. The reasonably high value of spectroscopic quality factor X = 0.64, predicts efficient stimulated emission in the present host.…”

The assignment of absorption transitions has been done based on the earlier literature [23,24].…”
