摘　　要：报道了一种基于Nd:YAG晶体衍生光纤(NYDF)的915 nm单频光纤激光器。使用掺杂原子数分数为2.5%的Nd:YAG晶体作为纤芯材料,高纯度石英管作为包层材料,利用熔芯法制备Nd:YAG晶体衍生光纤,其传输损耗为8 dB/m,在915 nm处其增益系数为1.16 dB/cm。基于Nd:YAG晶体衍生光纤,实现了一个稳定的915 nm单频光纤激光器,信噪比大于50 dB。实验结果表明Nd:YAG晶体衍生光纤有潜力应用于890~920 nm单频激光器。We reported a single-frequency fiber laser at 915 nm based on the neodymium-doped yttrium aluminum garnet(Nd:YAG)crystal-derived fiber(NYDF).Using Nd:YAG crystal with doped atomic number fraction of 2.5%as the core material and a high-purity silica tube as the cladding material,we fabricated the NYDF by the molten-core method.Its transmission loss was 8 dB/m and its gain coefficient at 915 nm was 1.16 dB/cm.A stable single-frequency fiber laser at 915 nm based on the NYDF was developed,with a signal-to-noise ratio of above 50 dB.The experimental results show that the NYDF is a promising candidate material for single-frequency lasers at 890 nm--920 nm waveband.
