Abstract

Liquid targets are capable of offering rapid refreshment for per shot, which makes it viable of using high repetition rate lasers. Here, we push the liquid targets to a low temperature condition. By generating a stable flowing line of liquid nitrogen in ambient environment, we successfully observe broadband terahertz wave generation under the excitation of subpicosecond laser pulses. This demonstration provides more possibilities in choosing potential materials for studying the THz wave generation process, and in understanding the laser-induced ionization from a new perspective.
