TTA Special Section on Terahertz Sources and Devices

摘要

The terahertz wave is considered to have great values and plentiful applications,such as in material science,analysis of molecular spectra,information and communication technology,biology and medical science,nondestructive evaluation,and national security.High-power widely tunable terahertz sources are required in the above practical applications of terahertz technologies.A promising approach for monochromatic terahertz generation is based on second-order nonlinear optical effect,
