Hello... I want to do femtosecond laser ablation based on TTM(two temperature model). Frist laser gives the energy to the electron and that electron heated up. Now, this electron gives its energy to ion grid and relax quickly. I want to build this model but I don't know how to couple electron temperature and ion grid temperature If someone knows about it please tell me. I want to see the temperature rise in the electron and iron grid.
