A numerical solution of the problem of nonstationary heating 
of a two-dimensional nanoparticle by laser radiation in the approximation 
of a constant temperature over the nanoparticle volume is presented. 
The asymptotes to the heating temperature for long times and for maximum 
heating of a nanoparticle at long durations of laser radiation have 
been obtained. It is shown that the temperatures of heating of silver 
and gold nanoparticles subjected to laser radiation at a resonance 
wavelength of plasmons are appreciable and may reach the boiling temperature 
of water.
