This paper studies numerically the temperature reached by atomic force microscope tips illuminated by femtosecond laser pulses, in which the laser focusing dependence of tip heating is investigated in detail and the laser heating effects on different tips are discussed too. The results show that tip heating can be significantly reduced if the femtosecond laser is focused tightly on the tip apex.
