A short absorption length ytterbium (Yb)-doped large-mode area (LMA) fiber is presented as
a step forward to mitigate the stern problem of nonlinear scatterings in a tandem pumping …

High concentration rare earth doped, large mode area (LMA) step-index fibers, which
feature a very high cladding absorption per unit length at the pump wavelength, high …

A single-frequency laser based on Yb: YAG crystal-derived silica fiber (YDSF) was
demonstrated. The YDSF was fabricated by a molten-core method with a doping …

We have proposed a novel segmented cladding fiber (SCF) design and the bending effects
were investigated in detail. The proposed SCF with large mode area properties has a …

A new design of segmented cladding fiber (SCF) was proposed and fabricated in silica
glass. The silica glass SCF had a central core and hexagonal wings with higher refractive …

In this work, we have proposed and optimized a segmented cladding fiber (SCF) with a large
mode area (LMA) consisting of a uniform core and a double cladding. The outer cladding of …

We report on demonstration of high energy pulse laser at 2 μm by employing a normal
dispersion fiber attained by a waveguide dispersion engineering. The normal dispersion …

In this paper we present numerical and experimental results revealing that the mode
instability threshold of highly Yb-doped, Ce/Al co-doped pedestal fibers is affected by the …

In this paper, the thermal-lens induced mode coupling in step-index large mode area fiber
laser is systematically investigated. The pertinent mode coupling coefficient is studied firstly …

We report a Yb-doped 25/400 phosphosilicate binary fiber with a pedestal structure by
conventional modified chemical vapor deposition (MCVD) technology and solution doping …
