Abstract

The free-electron laser (FEL) has achieved impressively high power levels at high efficiency in the millimeter wavelength regime. Recent advances in this regime include the incorporation of efficiency enhancement techniques, the successful operation of high-gain amplifiers and oscillators, and the design of more compact, more practical devices. In this review, the development of these relatively long wavelength FELs will be traced through the past decade. The major differences between these long wavelength devices and the infrared to ultraviolet FELs will be described. Finally, 'some of the technology issues particularly relevant to millimeter wave operation will be discussed.
