Influence of Pump Laser Phase and Amplitude Distortions on Terahertz Generation Efficiency
43rd International Conference on Infrared, Millimeter and Terahertz Waves, IRMMW-THz 2018, NagoyaNagoya, Japan, 9 Sep 2018 - 14 Sep 20182018-09-092018-09-14  GO
We analyze the impact of phase front and intensity profile distortions of the pump laser on the generation of narrowband terahertz radiation by difference frequency generation inperiodically poled Lithium Niobate (PPLN). A code employing finite difference method for beam propagation and nonlinear interaction in cylindrical symmetric system is developed. [...]

Design strategies for single-cycle ultrafast electron guns
After the first introduction of ultrafast electron guns for acceleration of particles using single-cycle electro-magnetic pulses, the basic structure has gained increasing interest as promising solutions for high gradient compact electron guns. The significant benefit of using transient ultrashort pulses in this acceleration scheme opens a realistic path towards gigavolt-per-meter acceleration gradients. [...]

Characterization of laser to RF ynthesis and synchronization techniques
Hamburg 100 pp. () = Masterarbeit, Technische Universität Hamburg-Harburg, 2018
High-precision and low noise time transfer between a master clock and slave sources has become essential for numerous scientific applications in the latest decades. This is, from the comparison of different optical clocks around the world, to high sensitivity imaging of astronomical objects using multi-telescope arrays and to next generation photon science facilities such as X-ray free-electron lasers (FELs).
