Abstract :
We present the preparation and nonlinear optical characterization of nanocolloidal solutions of Ge27Ga9Se64 glass with different concentrations. Their nonlinear absorption is studied using open aperture Z-scan technique. Optical band gap of the material is be tuned by changing the concentration of the solute in the solution. Nonlinearity increases with decrease in optical band gap which in turn depends on the concentrations of the nanocolloidal solutions.
