Compact diode stack end pumped Nd:YAG amplifier using core doped ceramics.
We report on a compact Nd:YAG amplifier emitting a maximum pulse energy of 14 mJ. By amplifying a passively Q-switched oscillator (M(2)<1.2) a good beam quality of M(2) approximately 1.7 wasExpand

The Photonic FEL: Toward a Handheld THz FEL
Low energy, slow wave, electron beam based radiation devices, like traveling wave tubes and Cerenkov freeelectron lasers, have the disadvantage that the gain seriously degrades when the operatingExpand

Coherent Cherenkov radiation and laser oscillation in a photonic crystal
We demonstrate that photonic crystals can be used to generate powerful and highly coherent Cherenkov radiation that is excited by the injection of a beam of free electrons. Using theoretical andExpand

Photonic Free-Electron Lasers
A photonic free-electron laser (pFEL) produces coherent Cerenkov radiation from a set of parallel electron beams streaming through a photonic crystal. The function of the crystal is to slow down theExpand

The design of a multi-beam electron gun for a photonic Free-Electron Laser
The photonic Free-Electron Laser (pFEL) is a novel slow-wave device which relies on a photonic crystal (PhC) to synchronize an electromagnetic wave with copropagating electron beams [1-3]. TheExpand

Study of beam focusing techniques for a power- and frequency scalable photonic free-electron laser
In this paper, we study the feasibility and suitability of two beam focusing techniques, i.e., Brillouin-and immersed flow, to be used in a novel device which can be up-scaled in power via increasingExpand

Single-mode power scaling in a multi-beam photonic free-electron laser
Multi-beam slow-wave devices, such as photonic free-electron lasers (pFEL), are promising for power up-scaling of THz sources. However, multi-beam concepts usually require wide and hence overmodedExpand

Method to map individual electromagnetic field components inside a photonic crystal.
We present a method to map the absolute electromagnetic field strength inside photonic crystals. We apply the method to map the dominant electric field component Ez of a two-dimensional photonicExpand
