In this survey the laser-tissue interaction has been considered, with particular attention to thermal effects. Then Pulse Intensity Fluence formula for the hiltherapy pulse was retrieved. Thereafter PIF formula was applied with the lasers parameters used in some medical laser application to compare PIF values. In our opinion, PIF formula is easier to better understand HILT features and its differences with LLLT and Continuous Wave (CW ) Power Lasers.
