A vortex laser with tunable spatial coherence and its application in imaging
Partially coherent vortex beams are a class of complex structured light characterized by finite spatial coherence. Their unique multi-dimensional degrees of freedom are actively driving advancements in fields like light manipulation. Conventionally, partially coherent vortex beams from a resonator are difficult to be t...
