Abstract
We explore theoretically and numerically the temporal contrast limitation of a self-referenced spectral interferometry measurement. An experimental confirmation is given by characterization and fine compression of hollow-core fiber generated sub-15 fs pulses, yielding an accurately measured coherent contrast of 50 dB on a ±400 fs time range.
摘要
我们从理论和数值两方面研究了自参考光谱干涉测量的时间对比度限制。通过对空心光纤产生的亚 15fs 脉冲进行特性描述和精细压缩，给出了实验验证，在±400fs 的时间范围内实现了精确测量的相干对比度为 50dB。
