Infrared light passes through the metal lens and is converted into violet light and focussed in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.

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 ...

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 ...

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or “up-convert” the frequency of short infrared light to the visible range. Up-conversion of light has ...

Organic Non-Linear Optical (NLO) Materials have emerged as a promising field of study within the realm of chemistry. These materials possess unique optical properties that enable the manipulation and ...
