High-power single-frequency fiber lasers with exceptional properties, such as mode-hop-
free and narrower linewidths, lower noise, and compact all-fiber designs, have been …

This paper describes and discusses visible fiber lasers that are excited by GaN laser diodes.
One of the attractive points of visible light is that the human eye is sensitive to it between 400 …

The current state of the art in infrared Bi-doped fiber laser research is reviewed. The relevant
fiber glass compositions and fiber technologies are introduced. Lasers operating on …

Bismuth (Bi) doped fibers have shown promising potential for lasers and amplifiers in the
1150-1500 nm and 1600-1800nm wavelength region. Bi-doped aluminosilicate …

The recent results on the new laser material–Bi-doped glasses and optical fibers are
reviewed. First, luminescence properties of various Bi-doped glasses are discussed. At last …

It is now almost twenty-five years since the first Erbium-Doped Fiber Amplifier (EDFA) was
demonstrated. Currently, the EDFA is one of the most important elements widely used in …

We report on a 25 W continuous wave narrow linewidth (< 2.3 MHz) 589 nm laser by efficient
(> 95%) coherent beam combination of two narrow linewidth (< 1.5 MHz) Raman fiber …

A watt-level all-fiber laser radiating at the wavelength of 1.7 μm in a continuous-wave regime
was developed by using bismuth-doped high-germania optical fiber. A maximum slope …

Bismuth-doped fiber lasers operating in the range 1300–1470 nm have been demonstrated
for the first time, to our knowledge. It has been shown that Bi-doped alumina-free …

A short Bi doped fiber laser operating in the wavelength region of 1160-1179 nm has been
demonstrated. The influence of unsaturable loss on laser performance is investigated …
