Abstract
In this paper we study defocusing and non-paraxial effects associated with nanosecond pulsed laser beam propagation through femtosecond laser generated plasmas. Simulations were performed using a non-reduced wave propagation equation to highlight the role of spatial beam shaping of the nanosecond pulse in improving the laser propagation characteristics. We show that optimizing the shape of the laser intensity profile at the focus using a beam with the ring-liked focus helps to reduce both defocusing and non-paraxial effects.
