Plasma Dispersion Induced Self-Focusing of a Vortex Laser Beam in Silicon

Your library or personal account may give you access

Abstract

In this work, we demonstrate the focusing of a Gaussian laser beam, in silicon, by a vortex-shaped beam where both beams are at a wavelength of 775nm, which can sharpen the beam's PSF to improve the resolution in laser scanning microscopy.
