摘要
在 Ho:YAG 单晶光纤（SCF）中演示了源标量轨道角动量（OAM）激光器的直接功率缩放。得益于这种光纤状几何结构的长增益区和大表面体积比，我们在 2.1 µm 波长处实现了 100 W 的光涡旋激光（OAM = ℏ），斜率效率高达 66.0%，据我们所知，这是 2 µm 光谱范围内原点标量角动量（OAM）激光的最高功率纪录，为直接产生高功率、高效率的结构光束开辟了一条新途径。本文章由计算机程序翻译，如有差异，请以英文原文为准。
100 W orbital angular momentum laser at 2 µm.
Direct power scaling of an at-source scalar orbital angular momentum (OAM) laser is demonstrated in a Ho:YAG single-crystal fiber (SCF). Benefiting from the long gain region and the large surface-to-volume ratio of this fiber-like geometric structure, a 100 W optical vortex laser (OAM = ℏ) with a high slope efficiency of 66.0% is achieved at 2.1 µm, which is, to the best of our knowledge, the record power of the at-source OAM laser in the 2 µm spectral range and opens a new route for direct generation of high-power, high-efficiency structure light beams.

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.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
