Experimental Study of Third Order Nonlinear Absorption in Pure and MG Doped Lithium Niobate Crystals

With the discovery of laser in 1960 various nonlinear effect arises, the origin of nonlinear optics lies in the nonlinear response of materials to the incident coherent radiation. Using pulsed Q switched Nd YAG Laser, we have observed the important phenomena i.e. third order nonlinear effect in the LiNbO3 crystals. In present work, I have performed an experiment using simple and sensitive single beam Z scan technique to measure nonlinear absorption in LiNbO3 crystals samples such as pure LiNbO3 crystal, 5mol Mg doped LiNbO3 crystal, and 7mol Mg doped LiNbO3 crystal.
