摘要
We proposed an approach for the generation of interference-pattern helico-conical beams(HCBs)both theoretically and experimentally.The HCBs exhibiting intricate fringe structures are obtained by exploiting amplitude modulation and interference techniques.To precisely control the optical field distributions,we manipulate the azimuthal term within the helicoconical phase expression,presenting several illustrative cases that highlight the versatility of our approach.Through further combinations,more sophisticated comprehensive HCB patterns are investigated.This study deepens our knowledge about spiral-like optical patterns and paves a new avenue for potential applications,especially in the fields of particle manipulation,nanostructure fabrication,and optical metrology.
