Abstract :
We present linear (n) and nonlinear (n2) refractive indices, linear absorption coefficient (α), optical conductivity (σ) and 3rd order nonlinear optical susceptibility (χ<;3>) of glasses: 32(SiO2):9(AlO1.5):31.5(CdF2):18.5(PbF2): 5.5(ZnF2):3.5(RE-F3)mol% (RE: Er3+ or Yb3+). Measurement techniques used are spectroscopic ellipsometry, nonlinear transmission and degenerate four wave mixing. It is found that the χ<;3>, α, σ and n2 values of Er3+-doped glass are higher than that for Yb3+-doped glass at 532 nm.
