1. Thank you for your kind suggestion. I modify “thesis” to “article” 2. Eq.8 is a symbolic representation of Eq.7. V represents spin-orbit coupling (SOC) without vibration. F corresponds to Franck-Condon integrals. In this manuscript, we focus on the contribution from vibration. Hence, we simplify the effect of SOC to a constant. Considering vibration and thermal, F is solved by Jortner theory. Around Eq.8, we revise our manuscript to clarify the relation between Eq.7 and Eq.8 and the meaning of symbols in Eq.8. 3. Our manuscript figures out the angular transfer during all-optical switching, which is rarely discussed in other researches. In the original manuscript, the last paragraph in section 3 is a little confusing. We separate two questions and respectively explain the cause of problem. Firstly, we limit our model to a finite intensity of laser. Because high intensity of laser cannot be treated as perturbation in Hamiltonian. Secondly, we figure out the influence of the mismatch to final result. The breakdown of the area theorem may change the period of Rabi oscillation, but it will not influence of Rabi oscillation. Hence, we delete the area theorem related content in our manuscript. In summary, two questions are not fatal but flaw problems.

We separately discuss two questions and explain the origin of problem. Firstly, we limit our model to a finite intensity of laser. Because high intensity of laser cannot be treated as perturbation in Hamiltonian. Secondly, we set the mismatch Δℏ=1 as an example to figure out the influence of the mismatch to the final result. On the other hand, femtosecond laser has a relative broad frequency spectrum. The mismatch between incident laser and the energy gap is not large. The breakdown of the area theorem may change the period of Rabi oscillation, but it will not influence of Rabi oscillation. Hence, we delete the area theorem related content in our manuscript. According our model, we rename our system to “four-level system”. because our model involves four energy levels. Even though it is simple, the name — “four-level system” coincide with the dynamic of electrons. Thank you for your careful review of our manuscript. We have changed all mistake in the list and also carefully checked the manuscript again.
