surface area scattering to the levels of ?? ??????, would allow us to Enhance the sensitivity of ourchoice. With this context, other crystals may well most likely be used for optical isolators, like TGG orcavity applications. It truly is observed that TGP has the very best FoM for crystal lengths approximately ??0mm,In this paper, Er3+, Yb3+:CeF3 n
