A dinuclear complex [DyFe(CN)6(DMF)4(H2O)3] @ 1.25H2O (DMF = N, N-dimethylformamide) 1 based onthe cyanide as linkage was prepared and structurally characterize
The degradation of beam quality in large-core fiber is investigated experimentally. It is found that the output beam quality factor M2 is a compound tanh functi
