Nonlinear Optics is a well-established field of research, and a subject that has been the flagship of part of the Optics Group in Recife since the late 70’s. Presently, our work focus on:

. Characterisation of optical nonlinearities in photonics materials;
. Development and improvements in nonlinear optical characterisation techniques.
