| 摘 要： | 采用标准单模石英光纤作为拉曼增益介质，光纤布拉格光栅作为谐振腔镜，研制了一台内腔级联拉曼光纤激光器。利用掺Yb双包层光纤激光器作为抽运源，实现了二级拉曼转换，在波长1176.8nm获得了309mW的最大输出功率，斜率效率接近51.5％。在小抽运功率下，发现拉曼光纤激光器的输出中存在重复周期约为2.9μs的脉冲序列；当抽运功率大于某一值时，上述脉冲消失，获得了十分稳定的连续输出。

Output Characteristics of a Cascaded Raman Fiber Laser |
| |
| Abstract: | A cascaded Raman fiber laser (RFL) based on standard mono mode silica fiber and fiber Bragg gratings is fabricated. Pumped by a Yb doped double clad fiber laser, output power of the second Stokes wave around 1176 nm is obtained. The maximal total output power of the RFL is up to 309 mW, and the slope efficiency of the 1176.8 nm output is about 51.5%. Pulses with a repetition rate of 2.9 μs are observed in the laser output when the pump power is near to the threshold. However, when the pump power reaches to a value high enough, stable continue wave output power is achieved. |
