Intense and Broadband THz Source using Laser-Induced Gas Plasma

Abstract : The objective of the Phase I project was to create a compact, intense, broadband pulsed terahertz source suitable for use in a time domain spectroscopy system. This new source will cover a spectral range from 0.1 to 20 THz with an average power of 10 mW. In addition, we proposed to demonstrate spectroscopic measurements of explosives and related compounds. In this investigation, we performed some experiments with a gas cell incorporated with an in-line phase compensator on the THz emission efficiency using different gases as the THz wave emitter at 1 atm pressure.
