几个周期的光脉冲在光谱重叠区域中的不同谐波之间的干涉对脉冲包络内的光载波的相位敏感。在10 μ m厚的β-硼酸钡晶体中，来自Si（001）的近表面三次谐波产生与二次谐波产生相结合，产生足够强的谐波发射，用于单次测量。我们建议使用这种技术来测量高能量5-fs脉冲的载波包络相位。
The interference between different harmonics of a few-cycle optical pulse in the region of the spectral overlap is sensitive to the phase of the optical carrier inside the pulse envelope. Near-surface third-harmonic generation from Si(001) combined with second-harmonic generation in a 10-mum -thick beta-barium borate crystal produces sufficiently strong harmonic emission for single-shot measurement. We propose using this technique to measure the carrier envelope phase of high-energy 5-fs pulses.
