Few-cycle THz generation for imaging and tomography applications

Phys Med Biol. 2002 Nov 7;47(21):3691-7. doi: 10.1088/0031-9155/47/21/303.

Abstract

The methods for generating few-cycle THz radiation from semiconductors without external applied fields are reviewed. Their spectral characteristics, efficiency and prospects for imaging and tomography at terahertz frequencies are discussed.
