研究了双色成丝产生的单周期脉冲的载波包络相位。我们观察到了该相位的一种特殊行为：所产生的脉冲的高频分量的相位随着两个颜色输入脉冲之间的相对相位而连续且线性地变化，而低频分量的相位只有两个离散值。利用能测定CEP的频率分辨光学门控，清楚地观察到了相行为的转变。我们发现，这种相位行为是由被动CEP稳定方案产生的单周期脉冲的独特特征。(C)2015年美国光学学会
Carrier-envelope phase (CEP) of single-cycle pulses generated through two-color filamentation has been investigated. We have observed a particular behavior of the phase: the phase of high-frequency components of the generated pulses changes continuously and linearly with the relative phase between the two-color input pulses, whereas the phase of the low-frequency components takes only two discrete values. The transition of the phase behavior has been clearly observed by using frequency-resolved optical gating capable of CEP determination. We have found out that such a phase behavior is a unique feature of single-cycle pulses generated with a passive CEP stabilization scheme. (C) 2015 Optical Society of America
