Abstract
A novel
$1.7 \mu \text{m}$
and
$2.4 \mu \text{m}$
dual-wavelength pumping scheme for a
$4.3 \mu \text{m}$
dysprosium (Dy3+)-doped chalcogenide fiber laser was theoretically demonstrated. It was attributed to the
$2.4 \mu \text{m}$
excited stated absorption (ESA,
$^{6}\text{H}_{\mathrm {13/2}} \to ^{6}\text{H}_{\mathrm {9/2}},^{6}\text{F}_{\mathrm {11/2}}$
transition). Theoretically, when the two pumps were 5 W and 2 W, respectively, a laser power of 1.5 W with an remarkable efficiency of 30.2% was obtained from the home-made Dy3+:Ga0.8As34.2Sb5S60 glass fiber with a loss coefficient of 3 dB/m and a Dy3+ concentration of
$3.67\times 10^{25}$
ions/m3. Results indicated that the dual-wavelength pumping scheme based on the gain fiber provides a potential way to
$4.3 \mu \text{m}$
dysprosium-doped chalcogenide fiber lasers.
期刊介绍:
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
