The scaling potential of beam-splitter-based coherent beam combination
Michael Mueller, Christopher Aleshire, Joachim Buldt +4
The impact of nonlinear refraction and residual absorption on the achievable peak and average power in beam-splitter-based coherent beam combination is analyzed theoretically. Whil…
Multipass cell for high-power few-cycle compression
Michael Mueller, Joachim Buldt, Henning Stark +2
A multipass cell for nonlinear compression to few-cycle pulse duration is introduced comprising dielectrically enhanced silver mirrors on silicon substrates. Spectral broadening wi…
Gas-plasma based generation of broadband THz radiation with 640 mW average power
Joachim Buldt, Henning Stark, Michael Mueller +3
We present a high-power source of broadband terahertz radiation covering the whole THz spectral region (0.1-30 THz). The two-color gas plasma generation process is driven by a stat…
