Fibers are undeniably one of the most successful solid-state active media for lasers to date.
The reason is to be found in the thin elongated geometry of the fiber which, in contrast to …

Silica-based optical fibers with an ultra-high Yb concentration were systematically studied.
Three the most commonly used in industry glass matrixes for active fiber core were …

We report on what we believe is the first demonstration of a monolithic counter tandem
pumped ytterbium-doped fiber amplifier based on conventional double-clad fiber. At the …

Using numerical simulations of thermally induced mode coupling we show how the
instability threshold can be substantially reduced if the pump or injected signal is modulated …

Laser cooling of a 5? cm long, 1? mm diameter ytterbium doped (6.56× 10^ 25 ions/m^ 3)
silica rod by 67? K from room temperature was achieved. For the pump source, a 100? W …

Ytterbium‐doped lanthanum titanate glasses were prepared by levitation melting for the
detailed characterization of the Yb 3+ \rmYb^3+ spectroscopic properties in the rare‐earth …

Abstract An Er 3+/Yb 3+ co-doped phosphate glass with an ultra-low thermal expansion
coefficient (55× 10− 7 K− 1) was developed. The EYAP5 glass (80Al (PO 3) 3–20AlF 3-1.5 …

Ytterbium (Yb^ 3+)-doped oxyfluoride SiO_2-Al_2O_3-CdF_2-PbF_2-YF_3 glass and nano-
glass-ceramic (ie glass-ceramics containing nanocrystals) single-index optical fibers were …

In this work we analyze the power scaling potential of amplifying multicore fibers (MCFs)
used in coherently combined systems. In particular, in this study we exemplarily consider rod …

Abstract Er 3+ and xYb 3+ co-doped CdO–V 2 O 5–P 2 O 5 invert glasses were studied
through their structural, optical and photoluminescent properties as a function of the …
