Optimizing the efficiency in high order harmonic generation optimization by two-color fields
We address the problem of the optimization of high-order harmonic generation by two laser fields of frequencies \(\) and \(\) respectively, through a theoretical approach. The parameters that are investigated are the two lasers intensities as well as the relative phase between the two fields. We show that a moderate, but significant increase of efficiency can be achieved in that context and give the domain of optimized parameters. Moreover, we quantitatively investigate the gain and set the limitation of the optimization using such coherent control methods.
