Detection of Ultra-Trace Heavy metals in Aerosols with pg^m3 Sensitivity Using Filament-Induced Fluorescence Spectroscopy
Yuezheng Wang, Lu Sun, Zhiwenqi An +5
Heavy metal pollution, particularly in the form of airborne aerosols such as lead (Pb), cadmium (Cd), mercury (Hg), and cobalt (Co), poses serious health and environmental risks, n…
Acoustic diagnostics of femtosecond laser filamentation
Binpeng Shang, Nan Zhang, Pengfei Qi +3
The promising application of femtosecond laser filamentation in atmospheric remote sensing brings imperative demand for diagnosing the spatiotemporal dynamics of filamentation. Aco…
Nanotips for 0.5THz scattering scanning near field microscopy
Zeliang Zhang, Pengfei Qi, Olga Kosavera +3
This manuscript demonstrates the theory, design, and simulation of scattering scanning near field microscopy (s-SNOM) in 0.5THz. A comprehensive simulation model of nanotips' geome…
Analysis of laser polarization state on remote induced plasma luminescence characteristics of filament in air
Yuezheng Wang, Zhi Zhang, Zeliang Zhang +3
The femtosecond laser filamentation is the result of the dynamic interplay between plasma self-focusing and defocusing generated by the multiphoton/tunnel ionization of air molecul…
Femtosecond Laser Filamentation in Atmospheric Turbulence

Coupled air lasing gain and Mie scattering loss: aerosol effect in filament-induced plasma spectroscopy
Jiayun Xue, Zhi Zhang, Yuezheng Wang +8
Femtosecond laser filament-induced plasma spectroscopy (FIPS) demonstrates great potentials in the remote sensing for identifying atmospheric pollutant molecules. Due to the widesp…
Remote Sensing of Trace Element in Sea Salt Aerosol with Sensitivity Level of 10 pg/m3
Yuezheng Wang, Nan Zhang, Jiayun Xue +6
Sea salt aerosols composed mainly of micrometer-sized sodium chloride particles not only pose a potential threat to human health and traffic safety, but also directly affect climat…
Filament based Ionizing Radiation Sensing Technology
Weiwei Liu, Jiewei Guo, Nan Zhang +7
Accidental exposure to overdose ionizing radiation will inevitably lead to severe biological damage, thus detecting and localizing radiation is essential. Traditional measurement t…
Sub-ppb aerosol detection at a distance of 30 meters by millijoule femtosecond laser pulse filamentation in air
Jiewei Guo, Zhi Zhang, Nan Zhang +8
In this work, sub-ppb aerosol detection is achieved by femtosecond laser filament with a single pulse energy of 4 mJ at a distance of 30 m. A concave mirror with an open aperture o…
