Comparing a traditional academic career path or BSD ('Big Shining Doctorate') with the real-life careers of four investigators. In a new perspective article, the four argue for more recognition of non ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

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 ...
