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…

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…

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…

Transverse Mode Instability

Cesar Jauregui, Christoph Stihler, Jens Limpert

This work presents a review on the effect of transverse mode instability in high-power fiber laser systems and the corresponding investigations led worldwide over the last decade.…

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…

Coherent Beam Combination of Ultrafast Fiber Lasers

Arno Klenke, Michael Müller, Henning Stark +4

The performance of fiber laser systems has drastically increased over recent decades, which has opened up new industrial and scientific applications for this technology. However, c…
