报道了一种多芯微结构光纤(MF)产生超连续谱的现象,利用钛宝石飞秒激光器产生的20 fs光脉冲序列,通过一段长约40 cm的多芯微结构光纤,获得了展宽超过600 nm的光谱(400~1000 nm),而且当耦合位置不同时,可以得到不同颜色的光谱成分。实验结果表明,由非规则填充气孔组成的多芯微结构光纤可以出现超强的非线性和超连续谱展宽。 A multi-core microstructured fiber (MF) was reported to produce supercontinuum. By using a 20 fs optical pulse sequence generated by a Ti: Femtosecond laser, a multi-core microstructured optical fiber with a length of 40 cm was obtained. 600 nm spectrum (400 ~ 1000 nm), and when the coupling position is different, you can get different color spectral components. Experimental results show that super-nonlinear and supercontinuum broadening can occur in multi-core microstructured fibers composed of irregularly filled pores.
