摘要
近年来,掺铥光纤激光器凭借其结构紧凑、光束质量好、量子效率高等优势得到了越来越多的关注。其中,高功率连续掺铥光纤激光器已经在医疗、军事安全、空间通信、大气污染检测、材料加工等众多领域有了重要应用。过去近20年时间里,高功率连续掺铥光纤激光器发展十分迅速,目前最高输出功率已达千瓦量级。本文从振荡器和放大系统两个方面对以往报道的高功率连续掺铥光纤激光器进行了回顾,并给出了关于未来发展趋势的一些看法。
In recent years,Thulium-doped fiber laser has attracted more and more attention because of its compact structure,near diffraction limit beam quality,and high quantum efficiency.Among these laser sources,high power continuous wave(CW)thulium-doped fiber lasers have been widely used in many fields,such as medical treatment,military security,space communication,air pollution detection,material processing,and so on.In the past 20 years,high power CW thulium-doped fiber lasers have developed rapidly,and the highest output power has reached kilowatt level.In this paper,the high power CW thulium-doped fiber lasers reported in the past are reviewed from the aspects of oscillator and amplification system,and some views on the future development trend are given.
