The quest for research in the field of Nonlinear Optics, at Shahjalal University of Science and Technology, started nearly two decades ago. It was 1996 and the field of Nonlinear Optics was totally new in Bangladesh. Nonlinear interaction of light with matter deals with the light-induced changes of the optical properties of a medium. In general, the observation of nonlinear optical effects requires the applications of lasers. Numerous nonlinear optical phenomena have been discovered since the discovery of lasers in 1961. Nonlinear Optics (a revolutionary extension of conventional linear optics promoted by laser technology) is a relatively new field with very attractive applications. Each nonlinear process involves the intense laser light inducing a nonlinear response in the medium and then the medium reacting to modify the optical fields in a nonlinear way.  Read More....
