采用平均功率为141.6 W的皮秒光纤激光泵浦一段国产七芯光子晶体光纤,获得了平均功率为104.2 W、连续光谱覆盖范围从750至1700 nm以上的超连续谱输出.详细研究了超连续光谱随泵浦功率增加的演变过程,并对基于该七芯光子晶体光纤的超连续谱光源的光谱拓展和功率提升潜力进行相关的分析和讨论.该研究结果对高功率超连续谱光源的发展具有一定的参考价值.
Using a picosecond fiber laser with an average power of 141.6 W, a homemade seven-core photonic crystal fiber was pumped to obtain a supercontinuum output with an average power of 104.2 W and a continuous spectral coverage of more than 750 to more than 1700 nm. Spectral evolution with the increase of pump power, and the related spectral analysis and discussion of the potential of the power enhancement based on the supercontinuum light source of the seven-core photonic crystal fiber.The results of the research on the development of high power supercontinuum light source Has a certain reference value.
