| 内容記述 | Dissociative tunneling ionization of nitric oxide (NO) in linearly polarized phase-locked two-color fem-tosecond intense laser fields (45 fs, λ=800 and 400 nm, total field intensity I=1×10^14 W/cm^2) has beenstudied by three-dimensional ion momentum imaging. The N+fragment produced by the dissociative ionization,NO→NO^+ + e^−→N^+ + O + e^−, exhibits a butterflylike momentum distribution peaked at finite angles withrespect to the laser polarization direction. In addition, a clear dependence on the relative phase between the twolaser fields is observed, showing that the tunneling ionization occurs efficiently when the electric field pointsfrom N to O. For the highest kinetic energy component, the observed orientation dependence is well explainedwith theoretical calculations by the weak-field asymptotic theory for the 2π highest occupied molecular orbital(HOMO). On the other hand, the peak angle shifts toward the laser polarization direction as the kinetic energydecreases, indicating that pathways other than direct ionization from the HOMO contribute to the dissociativeionization. | |||||
