Investigation of enhanced second harmonic generation in laser-induced air plasma
Shing Yiu Fu, Kareem J. Garriga Francis, Mervin Lim Pac Chong +2
We report a systematic investigation into the processes behind a near hundredfold enhanced second harmonic wave generated from a laser-induced air plasma, by examining the temporal…
Flowing cryogenic liquid target for terahertz wave generation
Yiwen E, Yuqi Cao, Fang Ling +1
Terahertz wave emission from condensed matter excited by intense laser pulses not only reflects the details in laser-matter interaction but also offers bright terahertz wave source…
Terahertz Nonlinear Index Extraction via Full-Phase Analysis
Kareem J. Garriga Francis, Mervin Lim Pac Chong, Yiwen E +1
We experimentally show the spectrally averaged nonlinear refractive index and absorption coefficient for liquid water, water vapor, α-pinene, and Si using a full-phase analysis in…
Broadband Terahertz Wave Emission from Liquid Metal
Yuqi Cao, Yiwen E, Pingjie Huang +1
Metals have been studied as terahertz sources for decades. Recent research has shown the potential of metals in generating extremely high THz pulse energy excited by intense laser…
Flat liquid jet as a highly efficient source of terahertz radiation
Anton N. Tcypkin, Evgenia A. Ponomareva, Sergey E. Putilin +6
Polar liquids are strong absorbers of electromagnetic waves in the terahertz range, therefore, historically such liquids have not been considered as good candidates for terahertz s…
Spatial Sampling of Terahertz Fields with Sub-wavelength Accuracy via Probe Beam Encoding
Jiapeng Zhao, Yiwen E, Kaia Williams +2
Recently, computational sampling methods have been implemented to spatially characterize terahertz (THz) fields. Previous methods usually rely on either specialized THz devices suc…
