Terahertz Free-Electron Laser Optical Design and Simulation (English Edition) [Kindle-editie] beoordelingen het boek quotes

The Free Electron Laser (FEL) provides a versatile method for producing laser light. Traditionally, FELs are complicated in design and occupy large research facilities. The primary goal of this thesis is to investigate a particular FEL design that is small in size and operates in the terahertz (THz) frequency regime. The optics materials requirements are explored for power levels ranging from mW to kW. Additionally, as part of a simpler design and in spite of the large amount of diffraction present at THz wavelengths, a waveguide will not be utilized as others have done previously. Laser beam clipping, which is defined as the absorption of the laser beam at the outer edges of the diffracted mode, and a shortened undulator are investigated as methods to support the elimination of the waveguide.
