摘要
研制了一台波长可调混合锁模掺铒光纤激光器.该激光器是由基于分光比为30∶70的耦合器和偏振控制器组成的Sagnac干涉仪构成.通过1 0 GHz的调制器的调制,得到重复率为9.998149 GHz,脉宽小于18 ps的锁模脉冲输出.该脉冲是近变换极限脉冲.
A wavelength tunable, hybrid mode-locking fiber ring laser is demonstrated. The laser incorporates a Sagnac interferometer,which is formed by a polarization controller and an additional coupler with the splitting rate of 30 ： 70 only. With 10 GHz signal modulation of the modulator,the pulse duration at the repetition rate of 9. 998149 GHz was less than 18 ps. The output pulse was nearly transform-limited.
