Laser and matter properties effect on the enhancement of THz waves energy generated during liquid jets double-pulse excitation

摘要

In this paper we present the results of both experimental and theoretical study of terahertz waves energy enhancement during liquid jets double-pulse excitation. The dependence of the terahertz radiation energy on mutual ratio of the pre-pulsc and signal pump energies is investigated. Temperature dependence in the case of double-pulse irradiation reveals unexpected features displaying both exponential growth and decrease with a 18° optimal value.
