Abstract: Abstract The third-order optical nonlinearities of Ag2Se nanocrystals were investigated by using Z-scan techniques. Large optical susceptibility χ(3) with the imaginary and real parts of 5.0 × 10−11 esu and −(3.0 ± 0.2) × 10−9 esu has been obtained under 1 mW laser excitation,… read more here.
