Abstract

The effect of strong magnetic fields on high-order harmonic generation is considered for the [Formula: see text] molecule and a two-dimensional hydrogen atom in intense laser fields. Exact solutions of the time-dependent Schrödinger equation reveals: (i) strong magnetic fields parallel to the laser polarization confine the ionized electron wavepacket thereby enhancing the intensity and extending the harmonic generation spectrum; (ii) strong magnetic fields in combination with intense circularly polarized laser pulses can be used to control even and odd harmonic generation in two-dimensional atoms.
