摘要

我们建议使用非简并级联四波混频过程在等离子体和介电体中有效地产生高次谐波。用一个简单的模型来估计典型激光等离子体和玻璃载玻片产生的谐波的时间持续时间和最大阶数。在等离子体的情况下，我们预计会有相当大的脉冲压缩，从8次谐波开始产生亚飞秒脉冲。

Application of highly nondegenerate cascaded four-wave mixing to high-order harmonic generation

We propose to use nondegenerate cascaded four-wave mixing processes for efficient high order harmonic generation in plasmas and dielectrics. A simple model is used to estimate the temporal duration and maximum order of the generated harmonics for both a typical laser-produced plasma and glass slide. In the plasma case, we expect considerable pulse compression, with the production of sub-femtosecond pulses starting from the 8th harmonic.
