报道了一种基于光纤耦合半导体可饱和吸收镜的1064 nm调Q锁模全光纤激光器作为种子源的166 W突发模脉冲光纤放大器。在976 nm处泵浦功率为230 W时,输出对应于74%的功率转换效率。脉冲的重复频率为20 kHz,脉冲能量为8.3 mJ,脉冲宽度为120 μs,在40 MHz的重复频率下产生了约800个锁模脉冲,在最大输出功率下,单个锁模脉冲的宽度为112 ps。为了避免对光纤的光学损伤,初始锁模脉冲被带宽受限的光纤光栅展宽到72 ps。经过两级放大后,脉冲宽度进一步展宽到112 ps,这是放大过程中脉冲群自相位调制的结果。
We report a 166 W burst mode pulse fiber amplifier seeded by a Q-switched mode-locked all-fiber laser at 1064 nm based on a fiber-coupled semiconductor saturable absorber mirror. With a pump power of 230 W at 976 nm, the output corresponds to a power conversion efficiency of 74%. The repetition rate of the burst pulse is 20 kHz, the burst energy is 8.3 mJ, and the burst duration is ∼ 20 μs, which including about 800 mode-locked pulses at a repetition rate of 40 MHz and the width of the individual mode-locked pulse is measured to be 112 ps at the maximum output power. To avoid optical damage to the fiber, the initial mode-locked pulses were stretched to 72 ps by a bandwidth-limited fiber bragg grating. After a two-stage preamplifier, the pulse width was further stretched to 112 ps, which is a result of self-phase modulation of the pulse burst during the amplification.
