In recent years, the exploitation of compact laser sources and amplifiers in fiber form has
found extensive applications in industrial and scientific fields. The fiber format offers …

The tremendous success of the deployment of silica-based fiber and waveguides in the
photonic network has motivated an investigation of highly functional photonic devices for …

The spectroscopic properties and thermal stability of Er 2 O 3 doped Bi 2 O 3–B 2 O 3–Na 2
O glasses are investigated experimentally. A close correlation is observed between the B 2 …

The spectroscopic properties of erbium-doped silicon dioxide, bismuth oxide, and sodium
oxide glasses are investigated based on Judd–Ofelt analysis for absorption spectra …

Er-doped phosphate glasses were fabricated by melt-quenching technique. The changes in
their thermal, structural and luminescence properties with the addition of Al 2 O 3, TiO 2 or …

Performance of high-concentration Er/sup 3+/-Yb/sup 3+/-codoped phosphate fiber
amplifiers in a copum** configuration is presented. Gain, noise figure, and output signal …

We generate 9.3-W continuous-wave 1535-nm multimode output from a 7.0-cm short-length
Er-Yb codoped phosphate fiber laser. A slope efficiency of 29% is obtained at pump powers …

The codo** effect mechanism of Al and P on the solubility enhancement of Er3+ ion in
SiO2 glass was clarified by electron spin− echo envelope modulation spectroscopy. It turned …

We present the experimental verification of a new type of an active nanostructured fiber
devoted to simultaneous laser emission at two wavelengths: 1040 nm and 1534 nm in the …
