Suppression of Intramolecular Vibrational Energy Redistribution by Intense CW-Laser Fields

Figure 5

Comparison of suppression efficiency of Stark shift detuning (present method) and static detuning approaches. Shown in each figure is population dynamics of 4-level system with phenomenological dephasing parameter𝛾=30 cm⁻¹ on |𝑚⟩. 𝑉₁ and 𝑉₂ are taken to be 30 cm⁻¹. Other parameters are taken to be (a) Ω=0 cm⁻¹, Δ=30 cm⁻¹, (b) Ω=300 cm⁻¹, Δ=30 cm⁻¹, (c) Ω=0 cm⁻¹, Δ=300 cm⁻¹, and (d) Ω=0 cm⁻¹, Δ=3000 cm⁻¹.
