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

Figure 2

Population dynamics of Bixon-Jortner model. The dark gray, light gray, and white areas correspond to the population of |𝑖⟩, |𝑓⟩, and |𝑚⟩, respectively. The hatched area denoted by IVR corresponds to the population distributed over background manifolds |𝐵_𝑗⟩. (a) |𝑚⟩ is taken to be the initial state. (b) Two CW-lasers, 𝑉₁ and 𝑉₂, are applied corresponding to the |𝑖⟩-|𝑚⟩ and |𝑚⟩-|𝑓⟩ transitions. Both 𝑉₁ and 𝑉₂ are taken to be 0.1Ω. (c) Intense CW-laser is introduced to make the helper state |ℎ⟩ strongly coupled with |𝑚⟩ together with the relatively weak lasers 𝑉₁ and 𝑉₂.
