Abstract
We demonstrate the first, to our knowledge, all-fiber ring cavity laser with light emission in the mid-infrared. For this purpose, a low-loss single-mode ZBLAN optical fiber coupler, a tapered pump combiner, and an inline polarization controller are specifically developed. These components are combined for the first time to our knowledge, along with an Er:ZBLAN fiber, to realize the ring cavity. The output power reaches 36 mW of continuous wave emission in the wavelength band of 2.8 μm. Two different pump wavelengths, 0.976 and 0.785 µm, are used to characterize the laser output. The investigation of polarization state impact on laser output reveals that polarization control suppresses mode competition, leading to improved output stability.
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.
