Abstract

We demonstrate formation of a complex, multi-wavelength, three-dimensional laser beam configuration with integrated metasurface optics. Our experiments support development of a compact Sr optical-lattice clock, which leverages magnetooptical trapping on atomic transitions at 461 nm and 689 nm without free-space optics. We integrate six, mm-scale metasurface optics on a fused-silica substrate and illuminate them with light from optical fibers. The metasurface optics provide full control of beam pointing, divergence, and polarization to create the laser configuration for a magneto-optical trap. We report the efficiency and integration of the three-dimensional visible laser configuration, demonstrating the versatility of metasurface optics for atomic laser cooling.
