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。
The experiment of producing supercontinuum in 10cm long photonic crystal fiber by using Ti: sapphire femtosecond laser to generate ultrashort laser pulses with repetition frequency of 80MHz and pulse width of 10fs was reported. The continuous spectrum with a broadening range of 450nm to 1100nm was obtained. Experiments were observed in the soliton self-frequency shift and high-order soliton splitting phenomenon, non-soliton radiation and subsequent spectrum to the short-wave direction is closely related to the expansion.
