New type of metasurface allows unprecedented laser control

Researchers have developed a single metasurface that can effectively tune the different properties of laser light, including wavelength, without the need of additional optical components. The metasurface can split light into multiple beams and control their shape and intensity in an independent, precise and power-efficient way.
