2-2-1 Laser-Induced Heating and Melting
The absorption of laser light by metal nanoparticles gives rise to a
succession of energy transformation processes.
These involve the successive excitation and relaxation of the metal electrons, its interaction with the lattice,i.e. electron-phonon relaxation and the phonon-phonon thermalization.
Afterwards, several thermal processes like melting or evaporation can be activated.
