Popis:	Using the classical molecular dynamics method, the influence of absorption of laser radiation on heat transfer and temperature distribution in silicon dioxide thin films is studied. It is revealed that heating the film to a temperature close to the melting point leads to the appearance of compressive stresses with an amplitude of about 800–1000 MPa. Such high stresses can cause a thermoelastic breakdown of films.
