| 摘 要： | 为了实现高重复频率和高功率的光脉冲，实验采用Er3+/Yb3+共掺双包层光纤作为增益介质，稳定的中心波长为976 nm的高功率半导体激光器作为泵浦源，利用非线性偏振旋转锁模技术，得到稳定的自起振锁模光脉冲。当泵浦功率为2.4 W时，激光器输出重复频率为8.829 MHz的连续锁模光脉冲，平均输出功率为52.5 mW，自起振锁模泵浦阈值功率为0.6 W，并观测到了稳定的高阶谐波锁模、调Q和调Q-锁模光脉冲输出。

| Abstract: | The passive harmonically mode-locked fiber ring laser with a small segment of Er3+/Yb3+ codoped double-clad fiber as gain medium,which is pumped by 976 nm LD laser and mode-locked exploiting the nonlinear polarization rotation technique,was successfully demonstrated for the generation of self-starting mode-locked pulses.When the laser was pumped at 2.4 W,stable mode-locked pulses were obtained at the repetition rate of 8.829 MHz through modulating the fiber polarization controllers.The average output power ... |
