Improving the longitudinal and radial forces of optical tweezers: A numerical study

The Advantages and Disadvantages of Using Structured High-Order but Single Laguerre–Gauss LGp0 Laser Beams

“…Here, we will envisage a spherical aberratio negative and consider its influence on ratios L Z and R Z . De found in [55], and it will be enough to examine the final results d The presence of a spherical aberration, particularly when it is n improve the longitudinal stability of optical tweezers, as show confirms that the presence of a positive or negative SA degrade mance of the trap when it is enlightened by a GLB. Concerning shows that it is substantially improved, especially for a negati tained in different ways [55].…”

“…Figure 15 confirms that the presence of a positive or negative SA degrades the longitudinal performance of the trap when it is enlightened by a GLB. Concerning the radial force, Figure 16 shows that it is substantially improved, especially for a negative SA, which can be obtained in different ways [55].…”

“…Here, we will envisage a spherical aberration that can be positive or negative and consider its influence on ratios Z L and Z R . Details of this study can be found in [55], and it will be enough to examine the final results depicted in Figures 14-16. The presence of a spherical aberration, particularly when it is negative, can significantly improve the longitudinal stability of optical tweezers, as shown in Figure 14.…”
