摘要：
We experimentally confirmed that additional CEP fluctuations induced in a hollow fiber increased with gas pressure. A gas pressure in the hollow fiber of between 2 and 2.5 atm results in both a short-pulse generation and the small CEP fluctuation. We also measured the carrier-envelope phase (CEP) fluctuations of spectrally broadened intense pulses that passed through a hollow fiber. An additional carrier-envelope phase fluctuation of 0.12 rad was induced in white light generated in the hollow fiber under the optimum gas pressure.
