摘要

This paper presents a novel U-shaped fiber surface-enhanced Raman scattering (SERS) spectra probe with high-performance remote sensing based on femtosecond laser ablation and deposition of photoreduced silver nanoparticles. As the width of the U-shaped structure is around 12 μm, the sensitivity is enhanced about four times more than that of a single-endface-based fiber SERS probe. The experiment r...
