Intense THz s-SNOM for nonlinearity engineering in nanoscale
Pengfei Qi, Zeliang zhang, Wenqi Qian +6
Terahertz (THz) nonlinear optics offer powerful tools to investigate and manipulate electronic dynamics in condensed matter. Confining high-peak-power THz pulses within near field…
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…
Femtosecond Laser Filamentation in Atmospheric Turbulence
Jiewei Guo, Lu Sun, Yuezheng Wang +7
The effects of turbulence intensity and turbulence region on the distribution of femtosecond laser filaments are experimentally elaborated. Through the ultrasonic signals emitted b…
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…
