Nonlinear optics is a branch of optics that deals with the complex nonlinear relationships between the optical response of the medium and the incident light when it interacts with the optical medium.

Lithium niobite (LN) with an ultra-wide optical transparent window has shown excellent nonlinear, electro-optic, acoustic-optic, piezoelectric, thermoelectric and photorefractive effects. It is an ...

Nonlinear elasticity models form the theoretical backbone for predicting and optimising the behaviour of structural elements subjected to large deformations. Unlike linear theories, they account ...
