Partially coherent beams have a series of unique advantages for many application potentials. The correlation functions of conventional partially coherent beams satisfy the Gaussian distributions. Recently, great deal of attention has been paid to partially coherent beams with non-conventional correlation functions, and substantial progress has been made. In this short review, we first outline the fundamental theories on constructing correlation functions of partially coherent beams, and
then present detailed description of recent progress in our group along this line. It is shown that partially coherent beams with special correlation functions may offer several extraordinary properties, such as self-focusing, lateral shift of the intensity maximum, self-splitting, and self-
shaping, while promising application potentials in free-space optical communications and particle trapping can be expected. It is suggested that correlation function modulation represents a novel approach to manipulate the characteristics of light beams.
