锁模Yb光纤激光器的阿秒级定时抖动优化

Timing jitter optimization of mode-locked Yb-fiber lasers toward the attosecond regime

Youjian Song, Chur Kim, Kwangyun Jung, Hyoji Kim, Jungwon Kim

摘要:

我们展示了超低时间抖动的光脉冲序列,从自由运行,80 MHz的重复率,锁模Yb光纤激光器。利用亚20阿秒分辨率的平衡光学互相关方法,研究了腔内色散接近于零(中心波长1040 nm,范围为-0.004 ~+0.002 ps ~ 2)时各种锁模条件下的定时抖动。当从10 kHz到40 MHz(奈奎斯特频率)偏移频率范围积分时,测得的最低均方根定时抖动为175阿秒,这相当于迄今为止自由运行锁模光纤激光器的创纪录低定时抖动。我们还从实验上找到了实现超低时间抖动和相对强度噪声的光纤激光器锁模条件。

英文摘要:

We demonstrate ultra-low timing jitter optical pulse trains from free- running, 80 MHz repetition rate, mode-locked Yb-fiber lasers. Timing jitter of various mode-locking conditions at close-to-zero intra-cavity dispersion (-0.004 to +0.002 ps2 range at 1040 nm center wavelength) is characterized using a sub-20-attosecond-resolution balanced optical cross-correlation method. The measured lowest rms timing jitter is 175 attoseconds when integrated from 10 kHz to 40 MHz (Nyquist frequency) offset frequency range, which corresponds to the record-low timing jitter from free-running mode-locked fiber lasers so far. We also experimentally found the mode-locking conditions of fiber lasers where both ultra-low timing jitter and relative intensity noise can be achieved.
