掺稀土光子玻璃在光纤通信、激光雷达、远程遥感、红外探测以及生物医疗等领域有着重要的应用前景.目前,所广泛采用的石英基光子玻璃存在稀土掺杂量低、发光带宽窄、声子能量大和增益系数低等本征因素,制约着相关材料和元器件的发展.因此,研究和发展新型光子玻璃和光纤以适应新波段尤其是近中红外材料与器件的需求非常必要.本文概述了掺稀土光子玻璃在光纤放大器和光纤激光器中的重要应用,归纳了实现近中红外发光与激光对稀土离子和基质材料的基本要求,重点阐述了发射波长在1.0,1.5,2.0和3.0?m波段掺稀土光子玻璃及光纤与元器件的最新研究进展,指出了掺稀土光子玻璃近中红外发光与激光所面临的挑战,对其未来的应用和发展方向做出了展望.
Rare earth photonic glass has important application prospects in the fields of optical fiber communication, laser radar, remote sensing, infrared detection and biomedical applications.At present, the widely used quartz-based photonic glass has the disadvantages of low doping amount of rare earth, narrow emission bandwidth, Intrinsic factors such as large energy and low gain coefficient constrain the development of related materials and components.Therefore, it is necessary to research and develop new photonic glass and optical fiber to meet the needs of new wave band especially near infrared materials and devices.This paper summarizes The important applications of rare earth-doped photonic glass in optical fiber amplifiers and fiber lasers are summarized, and the basic requirements of near-infrared light-emitting and laser for rare earth ions and matrix materials are summarized. The emission wavelengths of 1.0, 1.5, 2.0 and 3.0 μm Rare earth photonic glass and optical fibers and components of the latest research progress, pointed out that the rare earth-doped photonic glass near-infrared light and the challenges facing the laser, and its future applications and development prospects made.
