This research investigates the use of metasurface optics for precise control of optical energies in biomedical based laser applications.It demonstrates the generation of an abrupt autofocusing beam (AAF) through a nanophotonic metasurface, which enables selective delivery of optical energy to specific regions of interest which is useful for various biomedical applications.
