Description

technical field [0001] The invention belongs to the field of optical fiber communication materials, in particular to a Pr 3+ / Ho 3+ Doped ZAlFB optical fiber glass and its preparation method. Background technique [0002] The mid-infrared laser in the 2-3μm band is close to the absorption peak of water, which is extremely safe for human eyes. It can make human cells instantly heat up and gasify after irradiation, and cover the absorption bands of various toxic gases such as nitric oxide and methane. Therefore, mid-infrared lasers in the 2-3 μm band have important applications in the fields of national defense, medical treatment, sensing and material processing. Fiber lasers have become the focus of research in the field of mid-infrared lasers due to their advantages of good beam quality, high conversion efficiency and small size. As the gain medium of fiber laser, rare earth ion doped glass fiber plays a decisive role in the performance of fiber laser. In terms of rare e...
