The technique of stimulated Raman shortcut to adiabatic passage (STIRSAP) is implemented to chainwise and N-pod systems. In chainwise systems, for large detuning conditions, the population of the middle states can be suppressed during the time evolution of the system and therefore, the Hamiltonian of an N-state system is reduced to an effective two-level system, using adiabatic elimination technique. Applying the STIRSAP method in two-level systems, the modified Rabi frequencies for fast population transfer are achieved. For N + 1-pod systems, assuming that N Stokes pulses have the same time dependence, we reduce the Hamiltonian of the original system to a three-state system. For both resonance and detuning conditions, we can reduce the three-state Hamiltonian to an effective two-state one. Using the STIRSAP technique, robust population transfer can be achieved from an initial ground state to an arbitrary coherent superposition of all ground states.

绝热通道受激拉曼捷径 (STIRSAP) 技术已应用于链式和N- pod 系统。在chainwise系统中，对于大的失谐条件，在系统的时间演化过程中可以抑制中间态的种群，因此，使用绝热消除技术将N态系统的哈密顿量简化为有效的两级系统. 在两级系统中应用 STIRSAP 方法，实现了用于快速种群转移的修正 Rabi 频率。对于N  + 1-pod 系统，假设NStokes 脉冲具有相同的时间依赖性，我们将原系统的哈密顿量简化为三态系统。对于共振和失谐条件，我们可以将三态哈密顿量减少到有效的二态哈密顿量。使用 STIRSAP 技术，可以实现从初始基态到所有基态的任意相干叠加的稳健种群转移。
