We report, to the best of our knowledge, the first monolithic erbium-doped fluorozirconate fiber laser bounded by two fiber Bragg gratings (FBGs) operating at 3.55 μm. Its output power and total optical efficiency are 5.6 W and 26.4% respectively, the highest ever achieved at this wavelength from a fiber laser. The monolithic design of the cavity also increases its stability and prevents fiber tip damage which has limited prior demonstrations to a maximum output power of 1.5 W. This Letter also studies the performances of the laser cavity for various output FBG reflectivities and presents numerical modeling results exhibiting remarkable agreement with experimental results.
据我们所知，我们首次报道了一种由两个光纤布拉格光栅（FBG）界定的单片掺铒氟锆酸盐光纤激光器，其工作波长为3.55μm。它的输出功率和总光效率分别为5.6W和26.4%，这是该波长下光纤激光器所达到的最高值。腔的单片设计还提高了其稳定性，并防止了光纤尖端损坏，而此前的演示因光纤尖端损坏限制了最大输出功率为1.5W。本文还研究了不同输出FBG反射率下激光腔的性能，并给出了与实验结果显著吻合的数值模拟结果。
