间隔0.256nm的多波长布里渊光纤激光器的实验研究
|
摘要
使用一个四端口环行器和两个三端口环形器,设计了一种波长间隔为0. 256 nm的多波长布里渊掺铒光纤激光器。该激光器中使用的两个三端口环行器组成的环腔产生一阶Stokes光,四端口环行器组成的环腔产生与入射进腔内的BP光相隔双倍布里渊频移的Stokes光。实验测试得到:当BP为3 d Bm、980 nm泵浦功率为27. 78 d Bm时,可得到波长间隔为0. 256 nm的6个波长的激光输出,同时也讨论了Stokes光的数量与BP光功率和980 nm泵浦光功率之间的变化关系。
A tunable multi-wavelength Brillouin erbium fiber laser( MWBEFL) with 0. 256 nm spacing based on a four-port circulator and two three-port circulators was experimentally proposed. The fiber laser configuration formed by two ring cavities. One cavity consisting of two three-port circulators generated 1 st Stokes,and the other cavity consisting of a four-port circulator produced a double Brillouin frequency spacing Stokes signal separated from the injected BP light. The experimental results show that:when BP is 3 d Bm and 980 nm pump power is 27. 78 d Bm,6 output channels with 0. 256 nm spacing can be obtained. And the relationship between the number of the Stokes signal and BP power and the 980 nm pump power is discussed.
