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.

Methods: A cohort of 197 EC patients, initially classified as stage I under FIGO 2009, underwent restaging based on the updated FIGO 2023 criteria. The patients' molecular and histopathological characteristics were documented, and their impact on upstaging was analyzed.
Dielectric metasurfaces, composed of planar arrays of subwavelength dielectric structures that collectively mimic the operation of conventional bulk optical elements, have revolutionized the field of optics by their potential in constructing high-efficiency and multi-functional optoelectronic systems on chip. The performance of a dielectric metasurface is largely determined by its constituent material, which is highly desired to have a high refractive index, low optical loss and wide bandgap, and at the same time, be fabrication friendly. Here, we present a new material platform based on tantalum pentoxide (TaO) for implementing high-performance dielectric metasurface optics over the ultraviolet and visible spectral region.

Secondary infection of the aorta is a sporadic and life-threatening disease. It is usually caused by infection and abscess in an adjacent structure. The most common mechanism for secondary aortic infection is a psoas abscess eroding the aortic wall, which rarely results in non-aneurysmal aortic rupture.
