Abstract:
We present the generation of high-power discrete
vortices formed by phase locking one-dimensional ring array of
lasers in a degenerate cavity. We have observed that the
divergence of discrete vortices is independent of the topological
charge, opposed to conventional continuous vortices. Further, we
have found that discrete vortices exhibit good self-healing abilities
against the obstructions in the source plane as well as propagated
plane.
