Varying pre-plasma properties to boost terahertz wave generation in liquids

Abstract

Terahertz frequency radiation provides a powerful tool for the investigation of matter from the life science to the solid state and plasmas. The authors experimentally and numerically present enhanced terahertz wave generation by single-color double-pulse excitation in flat liquid jets, providing a deeper understanding of the mechanism that underpins the terahertz generation in multi-pulse experiments.
