We have generated asymmetric aberration laser beams (aALBs) with auto-focusing properties. The asymmetry in the phase distribution of aALBs is deliberately exploited for controlling spatial intensity distribution, and ...

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 ...
