High‐power laser sources are widely used in industrial precision processing and act as a
new platform for strong‐field physics research using peak power over petawatt. This review …

The success of high-power fiber lasers is fueled by maturation of active and passive fibers,
combined with the availability of high-power fiber-based components. In this contribution, we …

We demonstrate that the strong 4-level Yb emission in a fiber laser can be almost completely
suppressed in an Yb all-solid double-clad photonic bandgap fiber, resulting in highly …

Ultrafast fiber lasers combining high peak power and excellent beam quality in the 1-µm
wavelength range have been explored to applications in industry, medicine and …

In this Letter, we demonstrate a monolithic high-power master oscillator power amplifier by
using a home-made double-clad tapered Yb-doped fiber (T-YDF) with an input end of∼ …

Efficient cladding-pumped three-level Yb fiber lasers are difficult to achieve due to the
competing four-level system and necessary high inversions. We demonstrate an efficiency …

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 …

There is still significant need for power scaling of fiber lasers. Large-mode-area fibers are a
key for the mitigation of optical nonlinearities. In recent years, mode instability has shown …

A rectangular-core large-mode-area photonic crystal fiber structure has been designed
based on the principle of higher order mode filtering by introducing fluorine-doped material …

Sepsis and septic shock exhibit a rapid course and a high fatality rate. Antibiotic treatment is
time-critical and precise knowledge of the antibiotic concentration during the patients' …
