啁啾激光场对H2+电离及解离的影响

Effect of chirp field on ionization and dissociation of H2+

摘要:

理论研究了2种不同啁啾激光场对H2+电离以及解离几率的影响. 结果表明：在2阶啁啾场下，H2+的电离和解离几率会随着啁啾参数由负向到正向的变化而呈现线性减小. 在3阶啁啾场下，H2+的电离和解离几率随着啁啾参数的变化呈现‘W’形结构，并且最大电离和解离出现在啁啾参数为0.01处.

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.
