Ultrashort and high intensity laser can induce high energy protons. Proton beams have a wide range of applications such as in the production of radioisotopes and proton therapy. An energy of the proton beam has a wide distribution. The distribution of activity in depth is calculated while laser induced protons are injected into an iron plate.
