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.

1.7 μm 和 2.4 μm 双波长泵浦 4.3 μm 掺镝钙钛矿光纤激光器建模

为4.3 \mu \text{m}$掺杂镝（Dy3+）的掺钙光纤激光器设计的新型1.7 \mu \text{m}$和2.4 \mu \text{m}$双波长泵浦方案在理论上得到了证实。它归因于 2.4 \mu \text{m}$ 激发声明吸收（ESA，$^{6}\{H}_{\mathrm {13/2}}\到 ^{6}text\{H}_{\mathrm {9/2}}, ^{6}text\{F}_{\mathrm {11/2}}$ 转变）。理论上，当两个泵浦的功率分别为 5 W 和 2 W 时，自制的 Dy3+:Ga0.8As34.2Sb5S60 玻璃光纤的损耗系数为 3 dB/m，Dy3+ 浓度为 3.67/times 10^{25}$ 离子/m3，可获得 1.5 W 的激光功率和 30.2% 的出色效率。结果表明，基于增益光纤的双波长泵浦方案为 4.3 \mu \text{m}$掺镝的掺钙光纤激光器提供了一种潜在的途径。

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.
