It is shown that when counterpropagating laser beams are incident on an array of parallel single-walled carbon nanotubes, strong interaction of waves is possible, accompanied by the amplification of one of the waves at the expense of another, more intense pump wave. The interaction is most efficient when the condition of phase matching of the incident waves and the slow plasmon polariton wave formed because of the laser-induced metallisation of nanotubes is satisfied. The dependence of the the signal wave gain on the geometric parameters of the array and the wave characteristics of the incident waves is studied numerically. A range of phase detuning values is found, in which the gain changes weakly near its maximum value.

结果表明，当反向传播的激光束入射在平行的单壁碳纳米管阵列上时，波的强相互作用是可能的，伴随着其中一个波的放大，而牺牲了另一个更强烈的泵浦波。当入射波和由于纳米管的激光诱导金属化而形成的慢等离子体激元波的相位匹配条件得到满足时，相互作用是最有效的。数值研究了信号波增益对阵列几何参数和入射波的波特性的依赖性。发现了一系列相位失谐值，其中增益在其最大值附近微弱地变化。
