摘要

本文探讨了由 LD 泵浦 Tm:YLF 激光器腔内泵送的 2.1 µm Ho:LaF3 激光器的激光特性。掺杂浓度为 2% 的 Ho:LaF3 晶体已被证实是一种新型激光增益材料，其 5I7 水平的发光寿命长达 25.7 ms。Ho:LaF3 激光器的平均输出功率为 2.07 W，斜率效率为 16.2%。双波长输出以 2089 纳米和 2093 纳米为中心，光斑质量极佳，M2x 和 M2y 值分别为 1.19 和 1.23。我们的研究结果有效证明了 Ho:LaF3 晶体在产生高功率 2.1 µm 中红外激光器方面的卓越能力。

2-W Ho:LaF3 laser intracavity pumped with a Tm:YLF laser

In this paper, we explore the laser properties of a 2.1 µm Ho:LaF3 laser intracavity pumped by a LD-pumped Tm:YLF laser. Ho:LaF3 crystals, with a doping concentration of 2%, have been verified as a novel type of laser gain material, whose luminescence lifetime of the 5I7 level was up to 25.7 ms. The Ho:LaF3 laser achieved an average output power of 2.07 W with a slope efficiency of 16.2%. The dual-wavelength output centered at 2089 nm and 2093 nm and exhibited excellent spot quality with M2x and M2y values of 1.19 and 1.23, respectively. Our results effectively demonstrate the impressive capability of Ho:LaF3 crystals for generating high-power 2.1 µm mid-infrared lasers.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
