Experimental generation of nonuniformly correlated partially coherent light beams

We report the experimental realization of nonuniformly correlated partially coherent light (NUCPCL) beams by passing laser beams through a phase-only spatial light modulator. The characteristics of NUCPCL beams whose coherence is of Gaussian distribution as well as inverse Gaussian distribution are studied theoretically and experimentally. It is shown that the experimental observations are in agreement with our theoretical analysis. NUCPCL beams may have some applications in optical manipulation.
