Observation of terahertz radiation via the two-color laser scheme with uncommon frequency ratios

LL Zhang, WM Wang, T Wu, R Zhang, SJ Zhang… - Physical Review Letters, 2017 - APS
In the widely studied two-color laser scheme for terahertz (THz) radiation from a gas, the
frequency ratio of the two lasers is usually fixed at ω 2/ω 1= 1: 2. We investigate THz …

Strong terahertz radiation from a liquid-water line

LL Zhang, WM Wang, T Wu, SJ Feng, K Kang… - Physical Review …, 2019 - APS
Terahertz radiation generation from liquid water has long been considered impossible due
to strong absorption. A few very recent works reported terahertz generation from water, but …

Tunable circularly polarized terahertz radiation from magnetized gas plasma

WM Wang, P Gibbon, ZM Sheng, YT Li - Physical review letters, 2015 - APS
It is shown, by simulation and theory, that circularly or elliptically polarized terahertz
radiation can be generated when a static magnetic (B) field is imposed on a gas target along …
