研究有自发辐射诱导相干效应的寿命拓宽的V-型原子与一个弱探测光场共振相互作用的情况。研究表明在激光与原子介质高度共振情况下。选择合适的参量.该系统中有暗孤子产生。同时孤子的群速度是慢光速。
In a lifetime-broadened V-type atomic medium with spontaneously generated coherence (SGC) and one weak probe field, the formation of optical solitons is studied. With proper parameters, dark solitons can be exhibited in this highly resonant medium. Meanwhile, the group velocity of the solitons is subluminal.
