Abstract

A multichannel calorimeter system is designed and constructed which is capable of delivering single-shot and broad-band spectral measurement of Terahertz radiation generated in intense laser-plasma interactions. The generation mechanism of backward THz radiation is studied using the multichannel calorimeter system in an intense picosecond laser-solid interaction experiment. The dependence of the BTR energy and spectrum on laser energy, target thickness and pre-plasma scale length is obtained. These results indicate that coherent transition radiation is responsible for the low frequency component (< 1 THz) of BTR. It is also observed that a largescale pre-plasma primarily enhance the high frequency component (> 3 THz) of BTR.
