Free-electron lasers (original) (raw)
ADS
Abstract
The evolution and basic principles of free-electron lasers are described together with their many applications. Free-electron lasers are tunable potentially powerful sources of coherent radiation over a broad range of wavelengths from the FIR to FUV regions of the spectrum. Free-electron lasers are uniquely suitable for operation at very high average power levels, making them attractive for military applications such as strategic defense. It is noted that free-electron lasers are expensive, especially in small sizes.
