已成功研制了一台大功率宽调谐范围光纤激光器,利用主动锁模技术实现了光纤激光器的稳定脉冲输出。实验中调节偏振控制器到合适位置和调制器偏压为3.8V时,获得了平均输出功率2.160mW,重复率9.970754GHz,中心波长为1561.200nm的锁模脉冲输出,输出脉冲中心波长在1528.015-1571.330nm之间连续可调。
A fiber ring laser with high power and wide-band tunable scope is successfully made. Using the active mode-locked technology, the stable mode-locked pulse can be obtained. By adjusting the polarization controller (PC) in a proper position and making the bias voltage of the modulator to be 3.8V, the laser operates a mode-locked state at 9. 970754 GHz repetition rate with 2. 160mW average output power,which is centered at 1561. 200rim. The output pulses can be tunable from 1528. 015 - 1571. 330nm.
