Fibre lasers are now associated with high average powers and very high beam qualities.
Both these characteristics are required by many industrial, defence and scientific …

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 …

High-power laser delivery with near-diffraction-limited beam quality is typically limited to tens
of metres distances by nonlinearity-induced spectral broadening inside the glass core of …

Mode instabilities, ie the rapid fluctuations of the output beam of an optical fiber that occur
after a certain output power threshold is reached, have quickly become one of the most …

The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous
development in the past decade or so, transforming itself from a research curiosity to a major …

Self-similar fiber oscillators are a relatively new class of mode-locked lasers. In these lasers,
the self-similar evolution of a chirped parabolic pulse in normally-dispersive passive, active …

The first rare-earth-doped fiber lasers were operated in the early sixties and produced a few
milliwatts at a wavelength around 1 μm. For the next several decades, fiber lasers were little …

We review the main challenges and give design guidelines for high-peak-power high-
average-power fiber-based chirped-pulse amplification (CPA) systems. It is clearly pointed …

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 …

(57) ABSTRACT A system for optical amplification includes an optical fiber with a core
containing a gain medium Surrounded by a cladding, a seed light Source, a control light …
