Abstract: The features of the high-harmonic generation under conditions of simultaneous action of two laser pulses with different frequencies on graphene are investigated. For this purpose, a model based on a non-perturbative quantum kinetic equation was used. The normal incidence of short linearly polarized pulses with photon energies of 0.25 eV and 1.0 eV on the sample surface is considered. The polarization planes are chosen orthogonal to clearly identify nonlinear interaction effects. It is shown that under such conditions, the spectrum of high-frequency harmonics should be enriched and the efficiency of conversion of the energy of radiation incident on the sample to the high-frequency region should increase.

Keywords: high-harmonic, graphene monolayer, nonlinear effects, quantum kinetic equation.
