Gisela Eckhardt’s research on stimulated Raman scattering (SRS) made it possible to generate laser light at multiple frequencies.

An important nonlinear optical effect, SRS is also used to probe chemical structures, store and read quantum information and amplify optical signals in long-distance communications networks. (Photo: Courtesy of Marja Sunquist)
