h.gh.intensity.vortex beams with.tunable topological ch.rges and low coh.rence are h.gh.y.demanded in applications such.as inertial confinement fusion(ICF) and optical communication. h.wever, traditional optical vortices featuring nonuniform intensity.distributions are dramatically.restricted in application scenarios th.t require a h.gh.intensity.vortex beam owing to th.ir ineffective amplification resulting from th. intensity.dependent nonlinear effect. h.re, a low-coh.rence perfect vortex beam(PVB) with.a topological ch.rge as h.gh.as 140 is realized based on th. super-pixel wavefront-sh.ping tech.ique. More importantly. a globally.adaptive feedback algorith.(GAFA) is proposed to efficiently.suppress th. original intensity.fluctuation and ach.eve a flat-top PVB with.dramatically.reduced beam speckle contrast. Th. GAFA-based flat-top PVB generation meth.d can pave th. way.for h.gh.intensity.vortex beam generation,wh.ch.is crucial for potential applications in ICF, laser processing, optical communication and optical trapping.
