Nonlinear optics is a branch of optics that deals with various kinds of optical nonlinearities with the goal of identifying new and efficient nonlinear materials. The materials of interest include laser-active media, semiconductors, photonic crystals, and others, which may have the potential to host extreme light-matter interactions induced by high-intensity or high-repetition-rate ultrashort light pulses in the single and multiple filamentation regimes. 

Nonlinear optics is essential in the development of coherent broad-bandwidth light sources, pulse compression techniques, as well as generation of coherent broad-bandwidth radiation based on self-action effects of intense light pulses in wide aperture functional materials.

The product portfolio of LIGHT CONVERSION includes multiple laser sources such as PHAROS and CARBIDE femtosecond lasers, FLINT oscillators, and OPCPA systems widely used to investigate nonlinear phenomena.
