We present a coherently-combined femtosecond fiber CPA system based on a rod-type, Ytterbium-doped, multicore fiber with 4x4 cores. A high average power of up to 500 W (after combination and compression) could be achieved at 10 MHz repetition rate wi

Coherently combined 16 channel multicore fiber laser system
Autor: Klenke, A., Müller, M., Stark, H., Stutzki, F., Hupel, C., Schreiber, T., Tünnermann, A., Limpert, J.
We present a coherently combined laser amplifier with 16 channels from a multicore fiber in a proof-of-principle demonstration. Filled aperture beam splitting and combination together with temporal phasing is realized in a compact and low-component-c

Transverse single-mode operation in a passive large pitch fiber with more than 200 mm mode-field diameter
Autor: Steinkopff, A., Jauregui, C., Stutzki, F., Nold, J., Hupel, C., Haarlammert, N., Bierlich, J., Tünnermann, A., Limpert, J.
In this Letter, we present, to the best of our knowledge, the largest effective single-mode fiber reported to date. The employed waveguide is a passive large pitch fiber (LPF), which shows the core area scaling potential of such a fiber structure. In

Ring-up-doped fiber for the generation of more than 600 W single-mode narrow-band output at 1018 nm
Autor: Palma-Vega, G., Walbaum, T., Heinzig, M., Kuhn, S., Hupel, C., Hein, S., Feldkamp, G., Sattler, B., Nold, J., Haarlammert, N., Schreiber, T., Eberhardt, R., Tünnermann, A.
We present the amplification of a narrow-bandwidth signal at a wavelength of 1018 nm to a power exceeding 600 W with a stable output polarization state. The beam showed an excellent, nearly diffraction-limited beam quality. The high-power output coul

Modelling the refractive index behavior of Al,P-doped SiO2, fabricated by means of all-solution doping, in the vicinity of Al:P = 1:1
Autor: Kuhn, S., Hein, S., Hupel, C., Nold, J., Haarlammert, N., Schreiber, T., Eberhardt, R., Tünnermann, A.
A novel and simple solution doping technique is used to explore the refractive index behavior of Al,P-doped SiO2 in the vicinity of the Al:P-ratio of 1:1 at low doping concentrations (0.4 up to 2.0 mol% Al2O3 and/or P2O5). It is found that even if Al

Single mode 4.3 kW output power from a diode-pumped Yb-doped fiber amplifier
Autor: Beier, F., Hupel, C., Kuhn, S., Hein, S., Nold, J., Proske, F., Sattler, B., Liem, A., Jauregui, C., Limpert, J., Haarlammert, N., Schreiber, T., Eberhardt, R., Tünnermann, A.
We investigate the average power scaling of two diode-pumped Yb-doped fiber amplifiers emitting a diffraction-limited beam. The first fiber under investigation with a core diameter of 30 µm was able to amplify a 10 W narrow linewidth seed laser up t
