Abstract
The second- and third-order nonlinear optical properties of Magnesium Sulfite Hexahydrate (MgSO3.6H2O) were studied by Second-Harmonic Generation (SHG) and Degenerate Four-Wave Mixing (DFWM). Nanosecond pumping by Nd:YAG laser having a variable reflection output coupler was used. The effective quadratic (&khgr;(2)) and cubic (&khgr;(3)) nonlinear susceptibility values are obtained at room temperature. The dispersion of the nonlinear optical susceptibility of MgSO3.6H2O is also discussed.
