摘要: In laser-assisted collisions, a control field may fail if we cannot precisely synchronize the colliding particles and laser pulse. this paper, show that pulses are robust in situation can be obtained by sampling-based method to achieve desired charge transfer probability with limited sensitivity arrival time of pulses. The time-dependent wave packet an adaptive target scheme used optimal calculations based on adiabatic two-state model H + D+ collision system. Several samples different pulse times selected construct fields at two energies validity these examined tests additional samples. Excellent performance was both cases.
