(color online) From left to right: electric field of the laser field, the Bohmian trajectories with different initial positions, and the HHG spectra simulated with TDSE (black lines) and the Bohmian trajectory (red lines), respectively, (a)–(c) for the monochromatic laser field and (d)–(f) for the two-color laser field with β = 1, r = 1, s = 2, and ϕ = 0. Inset in panel (e) shows the enlargement of the Bohmian trajectory with the initial position x₀ = 0.3.
