Ultrafast fiber lasers have gained rapid advances in last decades for their intrinsic merits
such as potential of all-fiber format, excellent beam quality, superior power scalability, and …

This paper reviews current fibre laser technology and new directions that will improve their
performances. Grating technology and the ability to provide high power operation has driven …

The beam quality factor (or M 2-parameter) for linearly polarized (LP)-modes of a step-index
fiber is calculated in a closed form, as a function of the fiber V-number. It is shown that M 2 …

We studied the temporal evolution of the photodarkening effect in an Yb-doped silica LMA
fiber. The absorption spectra exhibit an increase in absorption in the visible and in the near …

Coherent beam combination offers a solution to the challenges associated with the power
handling capacity of individual fibres, however, the combined intensity profile strongly …

At present, increasing the output power of a single fiber laser is a problem worthy of
attention, and a fiber signal combiner which can carry high power and high beam quality is a …

Microneedles are an innovation in the field of medicine that have the potential to
revolutionize drug delivery, diagnostics, and cosmetic treatments. This innovation provides a …

We report on a novel scheme to fabricate a simple, cheap, and compact tunable fiber laser.
The tuning is realized by splicing a piece of single-mode fiber to one end of an active double …

The effect of various parameters that limit the performance of fiber lasers are calculated for
yttrium aluminum garnet (YAG) as the fiber core. The optimum core diameter, the optimum …

We have developed a new technique to produce a Yb-doped fused silica bulk glass which is
very well suited for fiber laser applications. The starting point is a liquid suspension of SiO 2 …
