【摘要】 使用一种新型有机材料马来酸掺杂聚苯胺作为可饱和吸收体,在掺铒全光纤激光振荡器中实现稳定的调Q运转。实验中,采用双臂探测法测得该材料的调制深度和可饱和吸收强度分别为13.9%和0.336 MW/cm~2,将其以薄膜三明治形式插入到光纤谐振腔中,最终获得了重复频率从33.78 kHz到87.01 kHz的范围内可调,最窄脉冲宽度为2.29μs,最大单脉冲能量为54.64 nJ的稳定调Q脉冲输出。马来酸掺杂聚苯胺可以被认为是脉冲光纤激光器应用及其它光电器件的良好候选者。更多还原

【Abstract】 Based on an organic nonlinear optical material,Maleic Acid-Doped Polyaniline(MADP)Saturable Absorber(SA),a stable Q-switched pulse operation was realized in an erbium-doped all-fiber laser for the first time. In this experiment,the modulation depth and saturable absorption intensity of the MADP-SA were measured at 13.9% and 0.336 MW/cm~2 using the twin detector technique,respectively.The MADP-SA is inserted into the fiber resonator in the form of a thin film sandwich. The stable Qswitched pulse operation are achieved with the repetition rate range from 33.78 kHz to 87.01 kHz,the narrowest pulse width of 2.29 μs and the maximum single pulse energy of 54.64 nJ. MADP can be considered as a good candidate for pulsed fiber laser applications and other optoelectronic devices.更多还原
