surface area scattering to the levels of ?? ??????, would permit us to Increase the sensitivity of ourvariety. With this context, other crystals may likely be utilized for optical isolators, like TGG orcavity programs. It is actually identified that TGP has the best FoM for crystal lengths as much as ??0mm,In this paper, Er3+, Yb3+:CeF3 nanoparticl
