Hhg is very important in atom physics . two aspects manifest the importance of studying hhg . on the one hand it can accelerate the development of non - perturbation theory ; on the other hand , the emission of hhg may supply a kind of coherent - light of short wavelengh and even be applied to the field of biology 高次諧波在強場原子物理中占用很重要的位置,對它的研究不僅系統地促進了非微擾理論的建立和發展;而且高次諧波發射將極可能為人們提供設備簡單,費用節省的全相干短波長光源。
