“…Therefore, we can classify a pFEL as a slow-wave FEL. As such the theoretical foundations of pFELs should be closely related to other types of slow-wave FELs, specifically, theČerenkov FEL [58,59,[72][73][74][75][76][77][78][79] or the Smith-Purcell FEL [57,60,61,[80][81][82][83][84][85]. Also, certain types of microwave tubes, including the traveling-wave tube, backward-wave oscillator or orotron, rely on the same physical principles as slow-wave FELs [8,[54][55][56][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101][102].…”

Coherent electromagnetic waves are extensively used in various fields of research and many applications. Almost every part of the electromagnetic spectrum, ranging from radio waves to hard X-rays, has been put to work for the benefit of mankind. Therefore, it is not surprising that, despite a huge variety of existing sources of electromagnetic waves, there is a continuous demand for novel sources with improved properties tailored to particular needs. An important, recent development in this ongoing strive for new sources is the use of materials that are periodically structured on the scale of the electromagnetic wavelength, so-called photonic crystals, which fundamentally control the emission of light. This control enables scientists to devise photonic-crystal lasers with unique properties. Examples are ultra-fast modulated lasers or lasers with ultra-low threshold. Due to the employment of small, wavelength sized structures, these lasers are inherently suited for operation in a chip-sized format. For instance, photonic-crystal lasers may very well complement diode lasers in lab-on-a-chip applications that greatly simplify the analysis of biological and chemical samples. To create an even wider applicability of photonic-crystal based lasers, it is crucial to provide many different frequency ranges in a compact format.
