Abstract

A detailed investigation is made of the spectral properties of several superfluorescence operations in Nd-doped and Er-doped silica fibres pumped by a 514.5 nm Ar ion laser. The study demonstrates the spectral narrowing processes in the operations of superfluorescence. In Nd-doped fibre, the higher gain at 1080 nm suppresses the emission at about 910 nm, but the authors have still realized, for the first time, superfluorescence in this wavelength band, and a 0.4 mW output was achieved in a double-pass configuration. Also, the process of change from superfluorescence to lasing was recorded and analysed.

High-power broadband singlemode Pr 3+ - doped fibre superfluorescence light source

Y. Shi, Ove Poulsen

A broadband Pr3+-doped silica-based fibre superfluorescence light source at 1049 nm is demonstrated. For ~4 m length of Pr3+-doped fibre, the authors obtain an output power of 60 mW and a linewidth of ~20 nm at a pump power of 190mW. The dependence of the peak emission wavelength on the wavelength of the pump is investigated. The intensity weighted average wavelength is stable with only a small fluctuation of ±0.2 nm for different pump powers.

Fluorescence and superfluorescence line narrowing and tunability of Nd/sup 3+/ doped fibers

The inhomogeneous behavior of the 1.06 /spl mu/m-neodymium transitions in doped optical fibers have been investigated, using the fluorescence line narrowing technique, pumping on the /sup 4/F/sub 3/2/ and /sup 4/F/sub 5/2/ sublevels at 4 K. Each observed transition has been identified. As the pump wavelength varies, the shift of the main fluorescence line is 40 nm, with the two pumping levels. We have studied the spectral behavior of the superfluorescence as a function of the pump wavelength, the temperature, and the absorbed power. The spectral evolution depends on /spl lambda//sub p/ with 19 nm-tuning range at low temperature. At 300 K, the quasihomogeneous behavior of the transition decreases the tunability to 14 nm. Based on these results, we present a simple technique permitting precise prediction of gain and spectral line shapes of superfluorescent Nd-doped fiber sources.>

Er3+ excited-state absorption in an erbium-doped silica fiber at the wavelengths 1490–1580 and 978 nm

Alexander V. Kir’yanov, Yuri O. Barmenkov, ANA DINORA GUZMAN CHAVEZ

The spectral features of Er 3+ excited-state absorption (ESA) in an erbium-doped silica fiber (EF) at the telecom wavelengths 1490–1580 nm and at the wavelength 978 nm are reported. The measurement of the EF nonlinear transmission coefficient upon pumping the fiber in these spectral ranges, supplied with a theoretical background, allows one to obtain the spectrally dependent ESA parameter for the EF, which is defined as the ratio of the ESA to the ground-state absorption cross section.
