High-order harmonic generation when the electron recombines with different nuclei of N₂ molecule along the y direction in the OPTC laser field with different relative phases (a) φ = 0, (b) φ = 0.3π, (c) φ = 0.4π, (d) φ = 0.5π. The green solid line H₁ shows the HHG when the electron recombines with the nucleus C₁ and the blue dashed line H₂ shows the HHG when the electron recombines with the nucleus C₂, respectively.
