| Abstract: | The structural, optical, and nonlinear optical properties of the manganese nanoparticles prepared by laser ablation in various liquids were investigated using the 532 and 1064 nm, 50 ps laser pulses. The TEM and spectral measurements showed temporal dynamics of size distribution of Mn nanoparticles in solutions. The nonlinear absorption (β = 2 × 10−10 and 4 × 10−11 cm W−1) and positive nonlinear refraction (γ = 8 × 10−15 and 2 × 10−14 cm2 W−1) of picosecond radiation were observed in the Mn colloidal suspensions using the 1064 and 532 nm radiation, respectively |
