Effect of chirp field on ionization and dissociation of H2+

Abstract:

The effects of two different chirped pulses on ionization and dissociation probabilities of H2+ have been investigated theoretically. The results show that for the case of two-order chirped pulse, the ionization and dissociation probabilities of H2+ are linearly decreased as chirp parameters change from negative values to positive values. For the case of three-order chirped pulse, the ionization and dissociation probabilities of H2+ present the ‘W’ structure as chirp parameters change, and the maximum ionization and dissociation appear at the chirp parameter being 0.01.
