Abstract

This study introduces an innovative liquid atomization method that utilizes an optical approach. The technique involves the precise deposition of a metal film at the end of a hollow optical fiber, using the photothermal effect to achieve highly efficient liquid atomization. In contrast to previous studies on optical atomizers, our research demonstrates substantial advancements, particularly in precision control and the extension of ejection distances. Furthermore, this study explores the potential applications of this technology in scenarios involving high-laser power. While atomization techniques are commonly observed in everyday life through spray mechanisms, our research significantly enhances precision control, making it particularly relevant to the biomedical field. In summary, our study contributes significantly to the evolution of atomization techniques, holding great promise for practical utilization in the future, especially in fields such as nanoprinting and biomedical applications. Our innovative approach opens up new possibilities for precise liquid atomization, expanding the horizons of applications across various domains.
