Second-harmonic generation is a nonlinear optical process that allows for the creation of low-power and compact light sources. Researchers in China discovered nanocrystal-in-glass composites exhibit a similar but different phenomenon called transverse second-harmonic generation that would allow for the creation of light sources with expanded capabilities.
