Terahertz Frequency Detection and Identification of Materials and Objects

Abstract

There is early demonstration of amplification of THz wave in laser induced air plasma in the workshop, however, solid state THz amplifiers, the workhorse of conventional electronics, still do not exist at THz frequencies but the workshop felt that devices based on QCL and SLED structures will soon be a practical possibility. For broadband generation it is likely that femtosecond pulsed fibre laser THz sources will replace the Ti:sapphire system because of their greater ruggedness together with the advantages of fibre delivery.
