Abstract

Laser beam shaping is an active discipline in optics owing to its importance to both illumination and detection processes. The formation of single or multiples optical vortices in a laser beam has taken on recent interest in areas ranging from electron and atom optics to astronomy. An optical vortex is characterized as a point node of destructive interference around which the phase varies by an integer multiple of 2 times π. Here we describe our efforts to create localized vortex cores using only the interference of several Gaussian profile laser beams, a method that may be particularly suited to the application of vortex modes to intense femtosecond laser pulses.
