| 摘 要： | 利用闪耀光栅构成可调谐Littrow外腔,对掺Yb3+双包层光纤激光器的波长调谐输出进行了实验研究.激光调谐输出波长范围70nm.针对光纤内的双折射效应对激光的输出功率的影响,实验中使用了在线光纤偏振控制器,从而有效地减小了调谐曲线的起伏及其与荧光谱的差别,并得到了窄线宽、线偏振、宽带调谐的激光输出.

| Abstract: | A Yb 3+ doped double clad fiber laser based on an external cavity in Littrow configuration is demonstrated. The laser wavelength is tunable over a range of 70 nm. Considering the effect of birefringence on output power, a polarization controller is used during the experiment. So the ripple of output power at every tunable wavelength and difference between the tuning curve and the fluorescence spectra of Yb 3+ doped fiber are reduced. A tunable laser output with narrow spectral line width and linear polarization is acquired. |
