Aberration correction was one of the most important and challenging parts of optical trapping systems. Many works try to overcome aberration which is due to trapping setup itself or refractive index mismatch of glass slab and nanoparticles solutions. In this article, we investigate a new method for aberration correction based on a nonlinear refractive index of materials. With the emitting laser to the trapped particle, the refractive index of the trapping site increases and as a result, its aberration reduce. In accordance, this method offers a simple and low-cost way for increasing trapping stiffness.
