Abstract

The numerical simulations results of resonance excitation of internal optical field of transparent spherical microparticles under irradiation by ultra-short laser pulse train are presented. It was determined that the most optimal tuning of incident radiation to assigned high-Q eigenresonance of a particle might be realized using varying a porousness of pulse in a train with linear frequency modulation of each pulse in a train (chirping). Analytical expressions were found for calculation of these parameters depending on laser pulse duration and frequency location of excited resonance.
