Abstract

We consider superposition of two paraxial two-dimensional half Pearcey laser beams. By the beam propagation method (BPM), we study the beam intensity distribution in focal plane. For superposition with zero phase delay between the beams, the simulation showed that focal spot has a width of 0.36 free-space wavelengths, while superposition with phase delay of π allows obtaining two focal spots with a width of 0.42 free-space wavelengths.
