摘要

THz wave emission from liquids under intense optical excitation provides a new way to generate intense and broadband THz signals. Here, we show that the use of water lines in place of water films as THz emitters to obtain stronger THz signals. In addition, we observe that the polarity of liquid has a significant influence on the THz wave generation. Besides paving the way to develop intense liquid THz sources, our report could be useful for the further study of laser-liquid interaction.
