摘要

我们展示了复杂、多波长、三维激光光束配置与集成元表面（MS）光学器件的形成。我们的实验支持了紧凑型 Sr 光晶格时钟的开发，它在 461 nm 和 689 nm 波长处利用磁光捕获，而无需大块自由空间光学器件。我们在熔融石英衬底上集成了六个毫米级的元表面，并用来自光纤的光照射它们。元表面可完全控制光束的指向、发散和偏振，从而为磁光陷阱创建激光配置。我们报告了可见激光光束配置的效率和集成度，证明了元表面光学技术适用于原子激光冷却。

Three-dimensional, multi-wavelength beam formation with integrated metasurface optics for Sr laser cooling.

We demonstrate the formation of a complex, multi-wavelength, three-dimensional laser beam configuration with integrated metasurface (MS) optics. Our experiments support the development of a compact Sr optical-lattice clock, which leverages magneto-optical trapping at 461 nm and 689 nm without bulk free-space optics. We integrate six mm-scale metasurfaces on a fused silica substrate and illuminate them with light from optical fibers. The metasurfaces 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 visible laser beam configuration, demonstrating the suitability of metasurface optics for atomic laser cooling.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
