Technion researchers have demonstrated, for the first time, that laser emissions can be created through the interaction of light and water waves. This “water-wave laser” could someday be used in tiny sensors that combine light waves, sound and water waves, or as a feature on microfluidic “lab-on-a-chip” devices used to study cell biology and to test new drug therapies. For now, the water-wave laser offers a “playground” for scientists studying the interaction of light and fluid at a scale smaller than the width of a human hair.

The study is the first bridge between two areas of research that were previously considered unrelated to one another: nonlinear optics and water waves...
