HIGH-ORDER HARMONIC-GENERATION IN INTENSE LASER AND MAGNETIC-FIELDS

The effect of strong magnetic fields on high-order harmonic generation is considered for the H-2(+) molecule and a two-dimensional hydrogen atom in intense laser fields. Exact solutions of the time-dependent Sc hrodinger equation reveals: (i) strong magnetic fields parallel to the laser polarization confine the ionized electron wavepacket thereby en hancing the intensity and extending the harmonic generation spectrum; (ii) strong magnetic fields in combination with intense circularly pol arized laser pulses can be used to control even and odd harmonic gener ation in two-dimensional atoms.
