However, it is a great challenge to design and generate super-long quasi-non-diffracting beams with sub-diffraction and sub-wavelength size. In this paper, a method based on the idea of compressing a normalized angular spectrum is developed, which makes it possible and provides a practical tool for the design of a quasi-non-diffracting beam with super-oscillatory sub-wavelength transverse size. It also presents a clear physical picture of the formation of super-oscillatory quasi-non-diffracting beams. Based on concepts of a local grating and super-oscillation, a lens was designed and fabricated for a working wavelength of λ = 632.8 nm. The validity of the idea of normalized angular spectrum compression was confirmed by both numerical investigations and experimental studies. An optical hollow needle with a length of more than 100λ was experimentally demonstrated, in which an optical hollow needle was observed with a sub-diffraction and sub-wavelength transverse size within a non-diffracting propagation distance of 94λ. Longer non-diffracting propagation distance is expected for a lens with larger radius and shorter effective wavelength.","is_dataset_classified":null,"base_score":3.6375861597263857,"endowment":3.6375861597263857,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"29092191","pmcid":null,"openalex_id":"https://openalex.org/W2766394785","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China (NSFC)","grant_id":"61177093","title":null},{"funder_name":"National Natural Science Foundation of China (NSFC)","grant_id":"61575031","title":null},{"funder_name":"Fundamental Research Funds for the Central Universities","grant_id":"106112016CDJZR125503","title":null},{"funder_name":"National Key Basic Research and Development Program of China","grant_id":"2013CBA01700","title":null},{"funder_name":"Program for New Century Excellent Talent in University","grant_id":"NCET-13-0629","title":null},{"funder_name":"University of Electronic Science and Technology of China (UESTC)","grant_id":"","title":null}],"total_grants":6,"fwci":1.9348,"citation_percentile":0.86706778,"influential_citations":0,"citation_trend":[{"year":2018,"count":4},{"year":2019,"count":4},{"year":2020,"count":5},{"year":2021,"count":2},{"year":2022,"count":5},{"year":2023,"count":7},{"year":2024,"count":1},{"year":2025,"count":7},{"year":2026,"count":2}],"oa_status":"gold","license":"https://doi.org/10.1364/OA_License_v1#VOR-OA","oa_locations":[{"url":"https://doi.org/10.1364/oe.25.027104","host_type":"journal"},{"url":"https://doi.org/10.1364/oe.25.027104","host_type":"publisher"},{"url":"https://www.osapublishing.org/viewmedia.cfm?URI=oe-25-22-27104&seq=0","host_type":"publisher"},{"url":"https://pubmed.ncbi.nlm.nih.gov/29092191","host_type":"repository"}],"fields_of_study":["Orbital Angular Momentum in Optics","Near-Field Optical Microscopy","Optical Coatings and Gratings"],"mesh_terms":[],"keywords":["Optics","Diffraction","Angular spectrum method","Wavelength","Lens (geology)","Physics","Diffraction grating","Beam (structure)","Diffraction efficiency","Transverse plane","RADIUS","Grating","Materials science","Computer science"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Sustainable cities and communities"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-28T16:04:23.329728Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
