Temperature Distribution in Focused Area of a Cell by Short Pulse Laser

Abstract:

For studying the effect between short laser pulse and red blood cell (RBC) in a more accurate and powerful way, the light beam characters of a focused femtosecond pulse are studied with a simulation method, and then, a mixed wave-propagating model (MWP) is put forward after analyzing these characters, in which, light beam is thought as propagating in a Gaussian focused shape. In addition, a mathematical processing and linear absorption model in the focused irradiated region of RBC is built based on analyzing its physical mechanism. Finally, the temperature distribution within the RBC is gotten by data simulating calculation, which shows that the temperature variety caused by linear absorption in the focal region is rather small.
