飞秒激光在光子晶体光纤中产生超连续光谱机制的实验研究
Femtosecond laser pulses with duration of 35?fs from a Ti:sapphire laser oscillator were coupled into this fiber,and then periodic color rings were observed from the side of the fiber when the supercontinuum light propagated along the fiber.
报道了利用飞秒脉冲激光与非均匀微结构光纤相互作用中产生超连续光谱后在非均匀微结构光纤传输中双折射拍频现象的研究 。
A random distributed microstructure fiber is demonstrated, and supercontinuum light with a spectrum more than one octave (390～1050 nm) was generated in 60 cm microstructure fiber by the femtosecond pulse laser with a duration of 35 fs and a energy of several nanojoules per pulse.
大空气比所带来的大折射率差能将传输的光场强烈地局域在纤芯中 ,大大增强了非线性效应 ,所以在 1～ 2cm的传输距离内 ,便有白光产生 ,传输 6 0cm后 ,输入的 2 4nm ,35fs飞秒脉冲就展宽成超过一个倍频程(Octave) ( 390～ 10 5 0nm)的超连续光谱 ,并且由于其包层具有非均匀分布的大小不等的空气孔 ,从而在传输过程中观察到由这种结构形成的非完全光子带隙影响下 ,侧向光泄露呈现颜色变化的新现
Two Ti:sapphire femtosecond laser systems with 10Hz、120fs、60mJ and 1kHz、120fs、1mJ were used to get the white continuum spectrum in the water ,PMMA and glass.
试验中分别利用10Hz、120fs、60mJ的掺钛蓝宝石激光脉冲和kHz、120fs、1mJ的掺钛蓝宝石激光脉冲,在玻璃,聚甲基丙烯酸甲酯(PMMA)和水中产生了白光连续谱,并测出了白光的光谱范围,实验结果显示白光谱宽分别为440-820nm,440-1100nm和400-750nm;从自聚焦和自相位调制理论出发,对白光产生的机理进行了讨论,结果显示自聚焦和自相位调制无法完整的解释PMMA的白光谱线。
