Abstract

Theoretically, this study investigates the influence of Gaussian beam spot size on the trapping forces exerted on dielectric particles by continuous and pulsed beams. We analyzed the dependence of trapping efficiency on spot size in terms of both the force value and force influence area. Our theoretical framework considers a dielectric sphere immersed in a water medium and irradiated by these beams. The results demonstrated that pulsed Gaussian beam achieves superior and more consistent trapping efficiency compared to continuous beam for a wider range of spot sizes.
