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…
Impact of thermo-optical effects in coherently-combined multicore fiber amplifiers
Albrecht Steinkopff, Cesar Jauregui, Christopher Aleshire +2
In this work we analyze the power scaling potential of amplifying multicore fibers (MCFs) used in coherently-combined systems. In particular, in this study we exemplarily consider…
Simplified Design of Optical Elements for Filled-Aperture Coherent Beam Combination
Christopher Aleshire, Albrecht Steinkopff, Cesar Jauregui +3
A simplification strategy for Segmented Mirror Splitters (SMS) used as beam combiners is presented. These devices are useful for compact beam division and combination of linear and…
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…
Electro-optically controlled divided-pulse amplification
Henning Stark, Michael Müller, Marco Kienel +3
A novel technique for divided-pulse amplification is presented in a proof-of-principle experiment. A pulse burst, cut out of the pulse train of a mode-locked oscillator, is amplifi…
10.4 kW coherently combined ultrafast fiber laser
Michael Müller, Christopher Aleshire, Arno Klenke +4
An ultrafast laser delivering 10.4 kW average output power based on coherent combination of twelve stepindex fiber amplifiers is presented. The system emits close-to-transform-limi…
