The superfluorescent fiber source (SFS) with tunable optical spectrum has shown great application potential in the sensing, imaging, and spectral combination. Here, we demonstrate for the first time a 2-kW-level wavelength and linewidth tunable SFS.

Nov 1, 2024 · Superfluorescent fiber source (SFS) has the characteristics of excellent temporal stability and broadband spectrum [1], which make it widely used in ghost imaging [2], high-precision fiber-optic gyroscopes [3], temporal coherence-tailorable vector source [4] and optical coherence tomography [5].

A superfluorescent fiber source (SFS) is a special fiber source that commonly possesses high temporal stability and a wide spectral linewidth. In this work, an all-fiberized linearly polarized SFS with, to our knowledge, record output power and near-diffraction-limited beam quality is …

Dec 1, 2024 · All-fiber MIR superfluorescence generation and amplification in Er 3+ -doped fluoride fiber has been demonstrated for the first time. Two home-made MIR side pump combiners based on evanescent wave side-coupling theory are …

In this manuscript, a high power broadband superfluorescent source (SFS) with linear polarization and near-diffraction-limited beam quality is achieved based on an ytterbium-doped (Yb-doped), all fiberized and polarization-maintained master oscillator power amplifier (MOPA) configuration.

The superfluorescent fiber source (SFS) has the unique features of broadband emission, low coherence, high brightness, and high temporal stability, thereby being applicable to a wide variety of situations such as sensing, medical imaging, and material processing.

In this paper, we demonstrate a high-power linearly polarized all-fiberized superfluorescent fiber source (SFS) with near-diffraction-limited beam quality. The laser system is based on a master oscillator power amplifier configuration, which mainly consists of a polarization-maintained (PM) broadband SFS and multistage PM fiber amplifiers.

Aug 24, 2016 · In this paper we demonstrate an all-fiberized superfluorescent fiber source that has a maximal output power of 2.53 kW and is based on a single-stage power amplification configuration. The seed source is a broadband-amplified spontaneous emission source with a full output power of 27.6 W.

Nov 1, 2024 · We demonstrated a kilowatt-level superfluorescent fiber source (SFS). The SFS has a wide linewidth tuning range of 2.71–27.25 nm, central wavelength tuning range of 1058–1080 nm, and an adjustable wavelength number of 1–7.

Aug 1, 2010 · We investigate a high-pumping-efficiency and linewidth-broadening, L-band, erbium-doped, superfluorescent fiber source (SFS) using a cascaded dual-backward-pumped configuration.
