Understanding two-photon double ionization of helium from the perspective of the characteristic time of dynamic transitions
Fei Li, Facheng Jin, Yujun Yang +4
By using the B-spline numerical method, we investigate a two-photon double-ionization (TPDI) process of helium in a high-frequency laser field with its frequency ranging from 1.6~a…
