Paper #2995 received 2016.03.11 revised manuscript received 2016.03.24; accepted for publication 2016.03.24; published online 2016.03.31.
The modelling of heating a spherical polystyrene microparticle by the laser beam having the wavelength 355 nm and varying spot size is described. The simulation results are presented for two different values of the beam spot radius. Nature experiments are reported aimed at measuring the velocity of a particle with the radius 5µm accelerated by microexplosion of the neighbouring particle.
