In this paper, we report a recent design and experimental results of an optical feedback technique for the setup of Collett-Wolf beam, which is a partially coherent source. A large negative and positive shift for a mirror with a dielectric slab backed by a metal is tested. The Collett-Wolf beam with Goos-Haenchen effect will further reduce speckle contrast by means of an ensemble average of many feedback beams.
