Ultrashort Laser Pulse Heating of Nanoparticles: Comparison of Theoretical Approaches
Figure 4
Kinetics of heating and cooling of a gold nanoparticle by a nanosecond laser
pulse of energy density 10 mJ/cm2 and duration 8 nanoseconds.
Calculations have been made by using OTM. (a) Illustration of the time dynamics
of laser heating of a 30-nm gold particle in different biological media: fat
(dashed-dotted curve), blood (dashed curve), tumor (solid curve), and prostate
(dotted curve). (b) Results of thermal calculations for a 35-nm gold particle:
heating and cooling in the water surrounding medium at different heat transfer
rates (solid curve), (dashed curve),
and (dashed-dotted curve).
