Measuring Thermal Load in Fiber Amplifiers in the Presence of Transversal Mode Instabilities
Franz Beier, Marco Plötner, Bettina Sattler +7
We report on detailed in-situ distributed temperature measurements inside a high power fiber amplifier. The deducted thermal load and the TMI-threshold of a commercial LMA fiber wi…
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…
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…
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…
