| 中文摘要: |
| 研制了一种采用非线性偏振旋转锁模效应的被动锁模掺Er3+飞秒激光器。利用性能稳定的980 nm激光二极管（LD）作为抽运光源，以高掺杂Er3+光纤为增益介质，在抽运功率为650 mW时，激光器锁模输出重复频率为31.25 MHz，平均输出功率为70 mW，中心波长为1560 nm，光脉冲宽度为163 fs的稳定飞秒脉冲激光。该激光器易于操作和调节，并且锁模状态稳定可以长时间的运行，其光纤结构更有利于小型化和便携化。 |
| 英文摘要: |
| A passively mode-locked fiber ring laser with a small segment of Er3+-doped fiber as gain medium, pumped by a stable 980 nm laser diode and mode-locked by the nonlinear polarization rotation (NPR) technique, was successfully achieved. When the laser was pumped at 650 mW, stable mode-locked pulses centered at 1560 nm with 163 fs pulse width. The repetition rate is 31.25 MHz. The laser presented here has advantages of being easy to operate and adjust, long-running and better stability. The fiber structure is of miniaturization, integration and portability. |
