我们对暴露于不同相对强度和非相称频率的两个激光场的叠加的一维模型原子的二色谐波响应进行了模拟。我们证明这种相互作用可以用来有效地生成非常紧密间隔的谐波的准连续体，并解释如何通过实验实现这样的方案。我们展示了如何用两个场之间的拍频来描述生成过程。最后，我们讨论 - 相互作用的局限性（已在其他地方进行了广泛研究）。
We present simulations of the two-colour harmonic response of a one-dimensional model atom exposed to a superposition of two laser fields of varying relative intensities and of non-commensurate frequencies. We show that this interaction can be used to efficiently generate a quasi-continuum of very closely spaced harmonics and explain how such a scheme can be implemented experimentally. We show how the generation process can be described in terms of the beat frequencies between the two fields. Finally, we discuss the limitations of the - interaction (which has been studied extensively elsewhere).
