摘    要:双包层掺镱光纤技术使高功率光纤激光器和放大器成为可能。最近几年随着制造技术和器件应用技术的发展双包层掺镱光纤也有了飞速发展,但是激光器的输出功率却受到受激拉曼散射和布里渊散射等非线性效应的限制,可以通过降低纤芯数值孔径、大模面积等方式来克服这种限制。分析和讨论了双包层掺镱光纤的激光放大原理、大模面积双包层掺镱光纤、多芯双包层掺镱光纤和微结构双包层掺镱光纤,介绍了掺镱光纤的研究现状和发展趋势。

关 键 词:双包层掺镱光纤  高功率光纤激光器  大模面积  多芯双包层掺镱光纤  微结构双包层掺镱光纤

Abstract:The advent of double cladding fiber technology has made high power fiber lasers and amplifiers possible. With developments in manufacture and devices incorporating, Ytterbium doped double cladding fibers have increased greatly over the past few years. However, the scalability of output power of fiber laser is limited by nonlinear effects such as stimulated Raman scattering and stimulated Brillouin scattering. These limitations can be overcome by using low core numerical apertures and large-mode areas, etc. Principle of double cladding Ytterbium doped fiber amplification, as well as large-mode area double cladding Ytterbium doped fiber, multi-core double cladding Ytterbium doped fiber and micro-structure double cladding Ytterbium doped fiber is discussed. Research status and development trend of double cladding Ytterbium doped fiber are introduced.
Keywords:double cladding Ytterbium doped fiber  high power fiber laser  large-mode area  multi-core double cladding Ytterbium doped fiber  micro-structure double cladding Ytterbium doped fiber
