Propagation properties and spatial shaping of partially coherent cosh-Gaussian beams

A partially coherent cosh-Gaussian (ChG) beam is introduced by means of adding a Gaussian term of the spatial degree of coherence. The analytical expression for partially coherent ChG beams propagating through a paraxial optical ABCD system is derived and used to study their propagation properties and spatial shaping. The intensity profile of partially coherent ChG beams can not remain unchanged upon propagation and depends on the propagation distance and decentered parameter, and on the spatial coherence parameter. By suitable variation of the decentered parameter and the spatial coherence parameter of partially coherent ChG beams at a fixed propagation distance, the spatial beam is shaped. The beam quality factor of partially coherent ChG beams decreases with increasing spatially coheren
