报道了一种基于zblan光纤的掺镨镱上转换光纤激光器,激光器工作在衍射受限的蓝绿波段。在491nm下,连续输出功率超过150mw,持续数小时而不退化。讨论了活性物质的光谱数据和包括振幅噪声在内的激光参数。
We report on a ZBLAN-fiber-based praseodymium-ytterbium-doped upconversion fiber laser operating in the blue-green with diffraction-limited beam quality. cw output powers of more than 150 mW at 491 nm are achieved for several hours without degradation. The spectroscopic data of the active material and laser parameters including the amplitude noise are discussed.
