摘要
高功率掺镱光纤激光器长时间工作会产生光子暗化现象,导致激光器输出功率降低,因此研究掺镱光纤光子暗化现象对促进掺镱光纤激光器的进一步发展具有重要意义。从产生机理、产生的影响以及抑制方法三方面,详细介绍了掺镱光纤光子暗化现象的研究进展,为光子暗化现象的深入研究提供参考。
The long time running of a high power Yb-doped fiber laser will cause photodarkening, which reduces the output power of laser. Thus, the research on photodarkening in Yb-doped fiber is of great significance to the development of Yb-doped fiber laser. The latest progress of photodarkening in Yb-doped fiber is detailedly introduced in three aspects including mechanism, impact and suppression method, which provides reference for the further study of the photodarkening.
