| 摘 要： | 报道了利用掺钛蓝宝石飞秒激光器产生重复频率为80MHz,脉宽为10fs的超短激光脉冲在10cm长光子晶体光纤产生超连续谱的实验,获得展宽范围为450nm到1100nm的连续谱。实验中观察到孤子自频移和高阶孤子分裂现象,非孤子辐射与随后光谱向短波方向的拓展有密切关系。

| Abstract: | An efficient supercontinuum generation in a photonic crystal fiber was demonstrated.A mode-locked Ti:sapphire laser was used to generate 80MHz repetition-rate 10fs pulse trains.The pulses were launched into a 10cm PCF and broadband continuum extending from 450nm to 1100nm was obtained.Soliton self-frequency shift effect as well as fission of higher-order solitons was observed in this experiment.Nonsolitonic radiation made the spectrum broaden at the short wavelength direction. |
