@book{Marek2023, abstract = {This work presents the development of a new sub-THz source for the generation of trains of coherent high-power ultra-short pulses at 263 GHz via passive mode-locking of two coupled helical gyro-TWTs. For the first time, it is shown that the operation of such passive mode-locked helical gyro-TWTs in the hard excitation regime is of particular importance to reach the optimal coherency of the generated pulses. This could be of particular interest for some new time-domain DNP-NMR methods.Umfang: XXV, 282 S.Preis: 52.00 €}, address = {Karlsruhe}, author = {Marek, Alexander}, doi = {10.5445/KSP/1000151835}, isbn = {978-3-7315-1250-9}, keyword = {passive Modenkopplung, Sub-THz, Gyro-TWT, Ultrakurze Pulse, passive mode-locking, sub-THz, gyro-TWT, ultra-short pulses}, month = {Jan}, pages = {324}, publisher = {KIT Scientific Publishing}, title = {New Type of sub-THz Oscillator and Amplifier Systems Based on Helical-Type Gyro-TWTs}, year = {2023} }
