Terahertz sources

What is it about?

A review of sources of terahertz frequency electromagnetic radiation. This is the part of the electromagnetic spectrum lying between visible light and radio waves. The emphasis is on radiation generated from surfaces. This covers both radiation stimulated by ultra-short pulses of laser radiation (optical pumping) and radiation generated by purely mechanical means. Both theoretical calculations and experimental data are covered.

Why is it important?

The specific topic of terahertz radiation from surfaces is dealt with in detail. This is set in the larger context of terahertz generation from a wide variety of sources - hence the title, "A review of terahertz sources". Yet even the review of terahertz sources is set in a wider context of terahertz science and technology, embracing terahertz detectors and components as well as sources. The emphasis is on recent developments. In this sense, the work gives a good current overview of the field.
