| 摘 要： | 为了获得一种被动锁模掺铒光纤振荡器及功率放大器，数值模拟出超短脉冲在光纤中的传输和演化过程，并基于此搭建了一种被动锁模掺铒光纤飞秒振荡器及功率放大器。实验获得了中心波长1560 nm、重复频率100 MHz、输出功率30 mW、脉冲宽度85 fs超短脉冲。通过采用PPLN晶体进行倍频，进一步获得了输出功率5 mW，中心波长780 nm的飞秒脉冲。该光纤激光器为全保偏光纤结构，具有体积小巧、可靠性高、稳定性好的特点。

| Abstract: | Based on the numerical simulation of the transmission and evolution of ultrashort pulses in the fiber, a passively mode-locked erbium-doped femtosecond fiber laser was developed. Ultrashort pulses with 1560 nm central wavelength of, 100 MHz repetition rate, 30 mW output power, and 80 fs pulse width was obtained. By using a PPLN crystal, the femtosecond pulse is frequency-doubled to 780 nm with 5 mW average power. The fiber laser system with all polarization-maintaining fibers could be compact in a small box facilitating high reliability and stability. |
