Abstract

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