Raman amplification and pulsed lasing in cladding-pumped germanosilicate fiber

We report for the first time Raman amplification in a cladding-pumped fiber. The double-clad germanosilicate fiber was pumped by a Q-switched Er-Yb co-doped fiber laser at 1570 nm. The power conversion efficiency was up to 36%, with a slope of 64%

Tunable Narrow Linewidth Erbium-Doped Fiber Ring Laser Based on Saturable Absorber and Self-Injection Feedback

IEEE Photonics Journal
We demonstrate a tunable single-longitudinal-mode (SLM) narrow linewidth erbium-doped fiber (EDF) ring laser (EDFRL) in a cost-effective way. The laser incorporates an unpumped-EDF-based saturable absorber (SA) and a self-injection feedback loop for mode

Linewidth and phase noise characteristics of DFB fibre lasers

, 2004
The anomalous linewidth behavior in a DFB fiber laser is investigated. It is shown that not only does the linewidth deviate drastically from the Schawlow-Townes linewidth formula by increasing with pump and laser power, but it also varies significantly ...

A New Design and Fabrication of Tapered Fiber-Based Loop Mirror as a Gain Flattened Erbium Doped Fiber Amplifier

Majlesi Journal of Electrical Engineering
The purpose of this study is flattening the amplified spontaneous emission (ASE) spectrum based on an erbium-doped fiber (EDF) by using a standard fiber-based loop mirror (FLM) and tapered fiber.

Dual Temperature and Strain Measurement with the Combined Fluorescence Lifetime and Bragg Wavelength Shift Approach in Doped Optical Fiber [PDF]

We have constructed fiber-optic sensors to measure temperature and strain by combining the properties of fiber Bragg gratings with the fluorescent lifetimes of various doped fibers.

Pump wavelength dependence of bismuth doped fibre laser

, 2008
We characterize Bi doped fibres in spectroscopic perspective under 915, 976 and 1090 nm pumping. The performance of Bi doped fibre lasers under different pumping bands is correlated to the spectroscopic characteristics.
