Nonlinear index explained by RP Photonics Encyclopedia

For transparent crystals and glasses n 2 is typically of the order of 10 −16 cm 2 /W to 10 −14 cm 2 /W Fused silica as used eg in silica fibers has a particularly low nonlinear index of 27 10 −16 cm 2 /W for wavelengths around 15 μm whereas some chalcogenide glasses exhibit several hundred times higher values Semiconductor materials also have very high nonlinear index
