Fruits are highly recommended nowadays in human diets because they are rich in vitamins, minerals, fibers and other necessary nutrients. The final stage of fruit production, known as ripening, plays a crucial role in determining the fruit’s quality

In this paper, we focus on the on-axis intensity evolutions of hollow beams in nonlinear media with a high nonlocality. It is found that, the evolutions of on-axis intensity with different beam powers are always periodic during propagation, whereas,

We investigate the propagation of Lorentz–Gauss beams (LGBs) for the case of the off-waist incident condition in strongly nonlocal nonlinear media (SNNM) and derive the analytical expression describing the beam width evolution of LGBs. We found tha
