| 摘 要： | 报道了一台全光纤结构主振荡功率放大(MOPA)型掺镱脉冲光纤激光器，以光纤光栅为腔镜，光纤型声光调Q的光纤激光器为种子源，通过两级掺镱双包层光纤放大器实现功率放大。对声光调Q的光纤激光器输出特性进行了研究，比较了不同泵浦波长、不同重复频率对激光输出功率和脉冲宽度的影响，并实现了最短脉冲宽度25 ns、单脉冲能量45 μJ的脉冲激光输出。在重复频率50 kHz时，对脉冲宽度130 ns、平均功率0.6 W的种子光进行放大，得到了平均功率102.5 W、脉冲宽度约240 ns的激光输出。

| Abstract: | An all-fiber pulsed Yb-doped fiber laser with master oscillator power amplifier (MOPA) structure is reported. The seed laser is an acousto-optic (AO) Q-switched fiber laser. The effect of repetition rate, pump wavelength on laser output power and pulse width are experimentally investigated. Finally, output laser with pulse width of 25 ns and pulse energy of 45 μJ is achieved at 10 kHz repetition rate. At repetition rate of 50 kHz, a seed laser with a 0.6 W output power is amplified in a two stage Yb-doped all-fiber amplifier system to a output power of 102.5 W. |
