Abstract
An overview of the experimental observation of the optical vortex streets was presented. The experiments were conducted in a 25-mm-long lithium triborate crystal cut for phase-matching for second-harmonic generation pumped at 1064 nm. The 8-ns pulses from a Q-switched Nd:YAG laser were used to pump the crystal. The screw-phase dislocations were nested in the pump beam by use of high-diffraction efficiency computer-generated off-axis holograms.
