Comparison of various liquids as sources of terahertz radiation from one-color laser filament

摘要

We show experimental results on the generation of terahertz radiation in at jets of modified water and variousliquids. We compare the change in the efficiency of the THz waves generation with a change in the pH and kHvalues, as well as the salt concentration in water and the fat level in milk. Dependences of the terahertz radiationenergy on the pump pulse energy are demonstrated.
