摘要
利用10GHz的主动锁模光纤激光器作为泵浦源,得到了25nm范围内平坦度为13dB的超连续谱。为实现其平坦化,实验中利用无源光纤光栅(FBG)滤波器对超连续谱进行了进一步的优化,使得25nm范围内平坦度<5dB,超连续谱的平坦度提高了至少8dB。
Supercontinuum with the power difference 3+ doped fiber laser as pumping source. In order to realize the flattening of Supercontinuum, the fiber Bragg grating filters were used to optimize the supercontinuum spectrum. As a result of the experiment the power difference <5 dB in the spectrum range of 25 nm was achieved. So the flatness of the supercontinuum was improved by at least 8 dB.
