Abstract

We experimentally study the UV and IR radiation impact on the dynamics of YAG:Yb3+ polycrystal microparticle levitated in a quadrupole Paul trap at atmospheric pressure. Micromotions of trapped particle are interpreted into instantaneous kinetic energy with a certain statistical mode. The microparticle kinetic energy statistical mode was determined for various powers of laser radiation. The kinetic energy statistical mode shows a nonlinear pattern with a dip at a power of 1.10 W for 1020 nm laser radiation. In turn, the dependence of the kinetic energy statistical mode on the power of 405 nm laser radiation remains monotonous. The kinetic energy dip of YAG:Yb3+ trapped microparticle under infrared radiation is discussed in terms of both the internal and the translational laser cooling
