en عمومى General پژوهشي Research <p>In this paper, the evaluation of time profile of a femtosecond pulse laser propagated through biological tissues is studied. The majority of the biological tissues with a high scattering anisotropy must be considered as turbid media, that their optical responses are complicated. To study the propagation of ultra-short pulse in turbid media, the diffuse equation is used. In this study, the analytical and numerical solution for diffuse equation is investigated. The numerical method is based on Boundary Integral method (BIM), and also, the time evaluation of propagating pulse is studied. </p> femtosecond pulse, scattering, diffuse equation, boundary element method, biological tissue 97 104 http://ijop.ir/browse.php?a_code=A-10-291-1&slc_lang=en&sid=1 Mohammad Ali Ansari m_ansari@sbu.ac.ir 10031947532846001023 10031947532846001023 Yes
