N1 - Massachusetts Institute of Technology, Masterarbeit, 2014 AB - Intense pulses of light with wavelengths, approximately ten times smaller than microwave sources and a hundred times larger than optical/near infra-red sources may be categorized as high-field Terahertz (THz) sources. By virtue of their large electromagnetic field amplitudes and relatively long wavelengths, they are uniquely amenable for electron acceleration, coherent X-ray generation and non-linear spectroscopy. Intra-pulse difference frequency generation or optical rectification of ultrafast optical pump pulses in non-linear crystals has emerged as the most efficient approach for high-field THz generation. Earlier theoretical treatment of these systems had predicted conversion efficiencies as high as 10 KW - Unveröffentlichte Hochschulschrift (GND) LB - PUB:(DE-HGF)19 UR - https://bib-pubdb1.desy.de/record/207668 ER -
