摘 要:提出了一种可自启动的全保偏“9”字腔光纤激光器,通过调节泵浦功率实现不同的多孤子脉冲输出。当泵浦功率达到224 mW时,激光器可实现多脉冲态锁模自启动,在维持锁模状态下泵浦功率最低可降至47 mW。激光器在泵浦功率为143 mW、101 mW、89 mW、76 mW、65 mW和55 mW时分别观察到松散束缚态脉冲、2~5个多孤子脉冲和稳定的单脉冲输出现象。脉冲重复频率均为8.68 MHz,其中松散束缚态脉冲的信噪比高达70.4 dB,主脉冲脉宽约为5.78 ps,相邻两脉冲间距约为50.04 ps;单脉冲状态下信噪比为65.8 dB,脉宽约为6.17 ps,平均输出功率为0.305 mW,单脉冲能量为0.035 nJ。此外,还测量了10 h内激光器的输出功率,证明了该结构具有高度稳定性。实验结果有助于进一步理解多孤子动力学,并且该激光器具有结构简单、可自启动、稳定性好、锁模脉冲可切换等优点,有广泛的实际应用价值。A self-starting all polarization-maintaining mode-locked figure-nine fiber laser was proposed,and different multi-soliton pulse output could be obtained by adjusting the pump power.When the pump power reached 224 mW,the laser could realize the self-starting of multi-pulse mode-locked state,and the pump power could be reduced to 47 mW under the mode-locked state.At the pump power of 143 mW,101 mW,89 mW,76 mW,65 mW and 55 mW,the output phenomena of loosely bound state pulses,2~5 multi-soliton pulses and stable single pulse were observed,respectively.The obtained soliton pulse repetition rate is 8.68 MHz.In the loosely bound state pulses,the signal-to-noise ratio(SNR)is as high as 70.4 dB,the main pulse width is 5.78 ps,and the spacing between two adjacent pulses is 50.04 ps.In the single-pulse state,the SNR is 65.8 dB,the pulse width is 6.17 ps,the average output power is 0.305 mW,and the single pulse energy is 0.035 nJ.In addition,the output power of the laser within 10 h was measured,demonstrating that the structure was highly stable.The experimental results are helpful for further understanding of multi-soliton dynamics,and the laser proposed has the advantages of simple structure,self-starting,good stability,and switchable mode-locked pulse,which is valuable for promoting the application of fiber lasers.
