Bright single-cycle terahertz source based on gas cells irradiated by two-color laser pulses

26 Nov 2019 Liseykina T. V. Popruzhenko S. V.

We study the excitation of electron currents in a transparent cell of sub-millimeter size filled by an atomic gas and illuminated by an intense two-color femtosecond laser pulse. The pulse consists of a strong fundamental component and its second harmonic of low intensity, both circularly polarized... (read more)
