Generation of a New Kind Partially Coherent Beam and Its Coherent Properties
Based on the coherent theory, the coherent properties of the new partially coherent beam were studied. The new partially coherent beam with the specific distribution of coherence was formed by the laser passing through a rotating special ground glass. The interference fringes produced by this beam passing through some double-holes with different hole spaces were experimentally recorded and their corresponding coherence degree was calculated. The coherence distributions of this beam under different propagation distances were experimentally investigated. The results show that, the coherence distributions of this beam are different with those of Gaussian Schell-model beams, and the degree of coherence increases with the increasing of propagation distances.
