In this paper, we report on the synthesis of terbium sesquioxide (Tb2O3) nanopowder by laser ablation a solid target material in Ar gas flow using an ytterbium fiber with average power 300 W. The as-synthesized nanoparticles featured spherical morphology, size 13 nm and substantially monoclinic crystal structure, whose symmetry was converted into cubic heat treatment at 850°C under vacuum.

We investigate the Kerr and magneto-optical effects for a probe laser field with two orthogonally polarized components, propagating in cold Rydberg atomic gas an inverted-Y-type level configuration via double electromagnetically induced transparency (EIT). Through approach beyond both mean-field ground-state approximations, we make detailed calculations on third-order nonlinear optical suscepti...
