摘要：

We have developed a remote sea salt aerosol fluorescence spectroscopy system integrating a high-power industrial-grade femtosecond laser to enhance detection sensitivity and precision in complex environments. This system successfully detects sea salt aerosol particles, achieving a detection limit of 0.015 ng/m(3) for neutral Na element (Na I) at 589 nm, with a detection range of 30 m. Our findings demonstrate significant improvements in remote aerosol monitoring, addressing previous challenges in long-range and high-precision sensing with a detection accuracy previously unattainable below 10 ng/m(3).
