Abstract

The retention stability of an aerosol particle in a quadrupole cell exposed to horizontal irradiation with a CO2 laser is investigated for several sizes of single spherical carbon particles. The stability of dynamic balance for the particle levitation is affected significantly by the irradiation and breaks down at a power higher than 105 W/m2. The particle is pushed away along the beam line, and its trajectory is slightly upward owing to the laser-induced aerosol heating.
