Comment on "Photoionization of helium atoms irradiated with intense vacuum ultraviolet free-electron laser light. Part II. Theoretical modeling of multiphoton and single-photon processes"

We question the conclusions reached by De Castro [Phys. Rev. A 72, 023410 (2005)] regarding the theoretical analysis of experimental results by Laarman [Phys. Rev. A 72, 023409 (2005)] on photoionization of He in the presence of a strong free-electron laser radiation pulse
