Abstract This paper describes and discusses visible fiber lasers that are excited by GaN laser diodes. One of the attractive points of visible light is that the human eye is sensitive to it between 400 and 700 nm, and therefore we can see applications in display technology. Of course, many other applications exist. First, we briefly review previously developed visible lasers in the gas, liquid, and solid-state phases and describe the history of primary solid-state visible laser research by focusing on rare-earth doped fluoride media, including glasses and crystals, to clarify the differences and the merits of primary solid-state visible lasers. We also demonstrate over 1 W operation of a Pr:WPFG fiber laser due to high-power GaN laser diodes and low-loss optical fibers (0.1 dB/m) made by waterproof fluoride glasses. This new optical fiber glass is based on an AlF 3 system fluoride glass, and its waterproof property is much better than the well known fluoride glass of ZBLAN. The configuration of primary visible fiber lasers promises highly efficient, cost-effective, and simple laser systems and will realize visible lasers with photon beam quality and quantity, such as high-power CW or tunable laser systems, compact ultraviolet lasers, and low-cost ultra-short pulse laser systems. We believe that primary visible fiber lasers, especially those excited by GaN laser diodes, will be effective tools for creating the next generation of research and light sources.

由 GaN 激光二极管激发的可见光光纤激光器

摘要 本文描述和讨论了由 GaN 激光二极管激发的可见光光纤激光器。可见光的吸引力之一是人眼对它的敏感度在400-700纳米之间,因此我们可以看到在显示技术中的应用。当然,还有许多其他应用程序。首先,我们简要回顾了以前开发的气态、液态和固态可见光激光器,并通过关注稀土掺杂的氟化物介质(包括玻璃和晶体)来描述初级固态可见光激光器研究的历史,以阐明初级固态可见光激光器的区别和优点。由于高功率 GaN 激光二极管和由防水氟化物玻璃制成的低损耗光纤 (0.1 dB/m),我们还展示了 Pr:WPFG 光纤激光器的超过 1 W 操作。这种新型光纤玻璃基于AlF 3 系氟化物玻璃,其防水性能远优于ZBLAN 众所周知的氟化物玻璃。初级可见光光纤激光器的配置有望实现高效、低成本、简单的激光系统,将实现具有光子束质量和数量的可见光激光器,如高功率连续或可调谐激光器系统、紧凑型紫外激光器和低成本超短脉冲激光系统。我们相信初级可见光光纤激光器,尤其是那些由 GaN 激光二极管激发的光纤激光器,将成为创建下一代研究和光源的有效工具。低成本、简单的激光系统,将实现具有光子束质量和数量的可见激光,如高功率连续或可调谐激光系统、紧凑型紫外激光器和低成本的超短脉冲激光系统。我们相信初级可见光光纤激光器,尤其是那些由 GaN 激光二极管激发的光纤激光器,将成为创建下一代研究和光源的有效工具。低成本、简单的激光系统,将实现具有光子束质量和数量的可见激光,如高功率连续或可调谐激光系统、紧凑型紫外激光器和低成本的超短脉冲激光系统。我们相信初级可见光光纤激光器,尤其是那些由 GaN 激光二极管激发的光纤激光器,将成为创建下一代研究和光源的有效工具。
