摘要
随着光纤激光器输出功率不断提高,高功率激光光纤的制备在工艺上要求更大尺寸的芯棒和对稀土掺杂光纤预制棒折射率分布更精确的控制。然而,多数现有的稀土掺杂石英光纤预制棒制备工艺是在通信光纤制备工艺的基础上发展而来的,其局限性逐步显现,因而迫切需要发展新工艺来制备高功率激光光纤预制棒。对一些制备稀土掺杂石英光纤预制棒的新工艺进行了介绍,并详细讨论了各工艺的优缺点。
Abstract
With increasing output power of fiber lasers, the fabrication of high power laser fiber requires larger sized core rod and more precise control of the refractive index profile of rare earth doped fiber preforms. However, most of the existing preparation techniques of rare earth doped silica fiber preforms are based on the processes which were used to produce communication fibers and their limitations have gradually emerged. Therefore, it is urgent to develop new techniques to fabricate high power laser fiber performs. In this paper, some newly developed preparation processes of rare earth doped silica fiber preform are elaborated, and then their advantages and shortcomings are discussed in detail.
