Gyrotrons, Electron
Cyclotron Masers, and
Free-Electron Lasers
11.1 INTRODUCTION
This chapter is devoted to a treatment of two classes of narrowband microwave sources with
demonstrated high power capability deep into the millimeter and even sub-millimeter wavelength
ranges: gyrotrons and electron cyclotron masers (ECMs), and free-electron lasers (FELs). In fact,
in this t ...
