对谐波产生的相干控制进行了理论研究。目标是一个特定的谐波顺序。采用最优控制理论求解带约束的驱动场。增加了额外的限制来抑制不希望的结果，如电离和解离。该方法是在频域中建立的。采用了一种基于松弛的场更新方法。通过几个实例对该方法进行了测试，证明了在受限频段的驱动场中可以产生高频。
Coherent control of harmonic generation was studied theoretically. A specific harmonic order was targeted. An optimal control theory was employed to find the driving field where restrictions were imposed on the frequency band. Additional restrictions were added to suppress undesired outcomes, such as ionization and dissociation. The method was formulated in the frequency domain. An update procedure for the field based on relaxation was employed. The method was tested on several examples demonstrating the generation of high frequencies from a driving field with a restricted frequency band.
