1 kW, 10 mJ, 120 fs coherently combined fiber CPA laser system
Henning Stark, Joachim Buldt, Michael Müller +2
An ultrafast fiber chirped-pulse amplification laser system based on coherent combination of 16 ytterbium-doped rod-type amplifiers is presented. It generates 10 mJ pulse energy at…
Kilowatt-average-power compression of millijoule pulses in a gas-filled multi-pass cell
Christian Grebing, Michael Müller, Joachim Buldt +2
We demonstrate the reliable generation of 1-mJ, 31-fs pulses with an average power of 1 kW by post-compression of 200-fs pulses from a coherently combined Yb:fiber laser system in…
Fiber laser-driven gas plasma-based generation of THz radiation with 50-mW average power
Joachim Buldt, Michael Müller, Henning Stark +2
We present on THz generation in the two-color gas plasma scheme driven by a high-power, ultrafast fiber laser system. The applied scheme is a promising approach for scaling the THz…
Investigation of spatiotemporal output beam profile instabilities from differentially pumped capillaries
Martin Gebhardt, Emmanuel B. Amuah, Robert Klas +4
Differentially pumped capillaries, i.e., capillaries operated in a pressure gradient environment, are widely used for nonlinear pulse compression. In this work, we show that strong…
23 mJ high-power fiber CPA system using electro-optically controlled divided-pulse amplification
Henning Stark, Joachim Buldt, Michael Müller +3
The pulse-energy scaling technique electro-optically controlled divided-pulse amplification is implemented in a high-power ultrafast fiber laser system based on coherent beam combi…
Temporal contrast enhancement of energeticlaser pulses by filtered self-phase-modulation broadened spectra
Joachim Buldt, Michael Mueller, Robert Klas +3
We present a novel approach for temporal contrast enhancement of energetic laserpulses by filtered SPM broadened spectra. A measured temporal contrast enhancement by at least 7 ord…
