摘要
‘Coherent control of high-harmonic generation in a two-color field’ has been widely concerned. Using split-operator algorithm, we have calculated the high-harmonic generation for helium ion He+ in a two-color field which is composed of a driving field and a weak subsidiary high frequency field (Is = I0/100, (ω,13ω),...(ω, 120ω)) and found that such a field can produce much higher harmonic intensity, typically increasing the harmonics corresponding to the incident frequency of the subsidiary field. The different effects coming from the different subsidiary fields are calculated and analyzed. It is indicated that one of the important underlying mechanisms is high frequency photon induced radiation.
二颜色的域里的高泛音的产生的协调控制广泛地被担心了。用裂口操作员算法，我们在高开车的域和一个弱附属公司镇静的二颜色的域里为氦离子He+计算了高泛音的产生频率地(是= I0/100 ，(， 13 )，...(， 120 ))并且发现如此的一块地能生产许多更高的泛音紧张，典型地增加相应于辅助的地的事件频率的泛音。来自不同的辅助的域的不同效果计算、分析。重要位于高频率光子下面机制之一是，这被显示导致的放射。
