Theoretical analysis on the efficiency of optical-optical double-color double-resonance multiphoton ionization

Analytic formula of the efficiency of optical-optical double-color double-resonance multi-photon ionization (OODR-MPI) is derived from the dynamic rate equation about the interaction of photon and material.Based on this formula, the influence of characteristic of the pump and probe laser on the ionization efficiency of (1+2+1) OODR-MPI process is simulated theoretically.It is shown that the pump laser will affect the ionization efficiency by the number control of the molecules excited to the first resonance state.The ionization efiiciency is decided by the probe laser directly.Both of the excited molecules and ionization efficiency increase with the intensity and pulse duration of the laser until saturation.It is also found that the longer the delay time of the probe laser to the pump one is, the lower the ionization efficiency would be.The delay time ought to be smaller than the lifetime of the excited molecule in the practical use of the OODR-MPI technique.
