Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

Nonlinear optical phenomena such as parametric amplification and frequency conversion are typically driven by external optical fields. Free electrons can also act as electromagnetic sources, offering ...

Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...

Nonlinear optics describes the regime in which the response of a material to an applied electromagnetic field depends nonlinearly on the field amplitude. Whereas in linear optics the induced ...

have found a new way to image layers of boron nitride that are only a single atom thick. This material is usually nearly invisible in optical microscopes because it has no optical resonances. To ...

Our research is focused on advancing the limits of light manipulation and application, driving innovation across optics, microscopy, and photonics. Dr. Mbaye Diouf is a tenure-track Assistant ...
